A. When you break it down to prime numbers: Ex. the prime factorization of 24: 24= 12 x 2= 3 x 4 x 2= 3 x 2 x 2 x 2 So the prime factorization of 24 is 3 x 2 x 2 x 2.

How do I teach students basic word problems that use prime factorization?
Q. I'm a substitute and need to teach students how to do a math word problem using prime factorization. They know how to do prime factorization, but how do I explain its use in a word problem? Here's an example: Julie is catering a party for 152 people. She wants to seat the same number of people at each table. She also wants between 2 and 10 people at each table. How many can she seat at each table? The answer is 4 or 8 people can be seated at a table. How do I explain why prime factorization solves this problem? Thank you!

A. Prime factorisation will allow you to see all the possible cases there are for the situation, and pick out the ones that fit the problem. 152 factorises to 2 x 2 x 2 x 19. From these, you'd pick out any combination of factors that, when multiplied, give an answer between 2 and 10. If you took 2 and 2, you'd have 4. The factors that you didn't take, 2 and 19, multiply together to give you the number of tables that are required. Taking 2, 2 and 2 give you 8 people on each of 19 tables Some smartmouth might say that you could just try to divide 152 by 3,4,5...but you could hit back and tell him to solve the problem that way when party is planned for 4848 people, and between 2 and 100 people per table are needed.

A. The question relates to two things: the first is to determine basically what numbers it takes multiplied together to create the final number in question. To do this, you start with the prime numbers, i.e., numbers which are only divisible by 1 and themselves. Several examples of these would be 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, and so on. Take 352, for example: 352/2 = 176 176/2 = 88 88/2 = 44 44/2 = 22 22/2 = 11 You have exhausted the number 2. Now move on to the next prime number by which 11 is divisible.

Asked by 11:11 - Sun Dec 16 16:40:11 2007 - - 4 Answers - 0 Comments
A. =2(x + 6)^2 Start with the original equation: 2x^2 + 24x + 72. You factor out the 2 from the first term (because it divides into all the terms evenly) to get: 2(x^2 + 12x + 36). Then factor what's left in the brackets (what two terms multiply to 36 and add to 12, which would be 6 and 6). Therefore you get: 2(x + 6)(x + 6). A term multiplied by itself is the same as squaring it, and thus, you get: 2(x + 6)^2.

And, the GCF of 4, 5, 9, and 7 is 1, so I believe this is right. So is this prime now? (I'm in 7th grade, and this isn't homework, I'm just working on my own)

A. Yes. In this case, this is correct. If you had two like variables, you would now combine them and continue to factor. Or, if you can divide the polynomial into two binomials that share a factor, you would be able to continue farther. But your polynomial doesn't fit either of these circumstances, so yours is as factored as possible.

What is the easiest way to learn prime factorization and apply it when reducing fractions to their lowest term
Q. I'm trying to reduce fractions to their lowest term using this method . Im just not understanding it. thanks
Asked by LFISCHER - Mon Feb 4 22:26:56 2008 - - 1 Answers - 0 Comments
A. My method is if the numerator and denominator are both even numbers, cut it in half. If they are still evens, cut it again. If you can sum the digits in both the numerator, sum the digits in the denominator, and they both total a number divisible by 3, divide each by 3. If there's a 5 or a 0 in both, you can divide both by 5. Usually this will do it. You may want to test 7, 11, 13 on both if you're really not sure. So you keep going until you get low enough to see for yourself it can't get any lower.

A. My method is if the numerator and denominator are both even numbers, cut it in half. If they are still evens, cut it again. If you can sum the digits in both the numerator, sum the digits in the denominator, and they both total a number divisible by 3, divide each by 3. If there's a 5 or a 0 in both, you can divide both by 5. Usually this will do it. You may want to test 7, 11, 13 on both if you're really not sure. So you keep going until you get low enough to see for yourself it can't get any lower.

A. There are several methods. My two favorites are the factor tree and successive division. factor tree: Start with the number to be factored at the top. Under it, split it two factors that you know of (any two). Repeat the splitting of anything that isn't prime until all the "leaves" are prime. ... 100 .../ ... \ ... 5 ... 20 ... / .. \ ... 4 ... 5 .../ .. \ ... 2 ... 2 Now just read the "leaves" to determine the prime factors. 2 x 2 x 5 x 5 = 100 successive division: Start with the number. Divide it by 2 as much as possible. When that is exhausted, try 3, then 5, then 7, then 11, etc. 100 / 2 = 50 50 / 2 = 25 25 / 5 = 5 5 / 5 = 1 Read the divisors: 2 x 2 x 5 x 5 = 100 lowest common multiple (LCM): As for figuring out the LCM,… [cont.]
