Factorization of 725 will not divide evenly in 72, so it is not in the factorization. An easy way to know if a number is divisible by 5 is to look at the digit in the ones place. If it is 0 or 5, it is divisible by 5. If any other number is in the one's place, the number is not divisible by 5.
All you do is write the prime factorization. I'll do an example: 50y First, you find the prime factorization of the coefficent using a factor tree, but it won't let me do that, so this is what the prime factorization should look like: 2x5x5 Then you add the variable: 2x5x5xy When you have a negative coefficent, just put a negative one in front of your answer. -50y = -1x2x5x5xy

The prime factorization of a number uses only primes. Ex: The prime factorization of 12 is not 6 x 2, and not 4 x 3, because 6 and 4 are not prime numbers. The prime factorization is 2 x 2 x 3. Their product is 12 and all factors are prime numbers. To get a prime factorization you are usually taught to factor through division by small prime numbers, sometimes you must use the same number more than once as in the example of 12 above 2 was used twice. Ex: find the prime factorization of 18. The smallest prime is 2... divide by 2 18 / 2 = 9 .... for the next step divide 9 by a prime 9 / 3 = 3 ... this is a prme ... it is also a factor so the prime factorization is 18 = 2x3x3 Ex. find the prime factorization of 35. 35 cannot be divided by 2, or 3, so use 5 first 35 / 5 = 7 .... since 7 is a prime we are finished. The prime factorization of 35 is 35 = 5 x 7 Some teachers teach this using a "factor tree" .. I can't type one of those on a computer.
Oh, what a happy little prime factorization we have here! Let's take a closer look. When we multiply 2 by 3 by 3 by 5, we get 90. So, this prime factorization is for the number 90. Isn't that just lovely?
2 x 3 x 5 x 7 = 210
