Question

How do i write the numbers as the product of their GCF and another sum. (Example please)

Answer 1

Let's assume we were given 2 numbers: 15 and 30. Their sum is:

We want to express it as the product of GCF and another sum.
15 is divisible by: 1, 3, 5, 15
30 is divisible by: 1, 2, 3, 5, 6, 10, 15, 30
The greatest number that appears in 2 series is 15.


In this case sum of two numbers can always be written as:

Answer 2

(20 + 10).....GCF = 10

(20 + 10) = (10 * 2) + (10 * 1) = 10(2 + 1)

here's another one..
(27 + 36).....GCF = 9

(27 + 36) = (9 * 3) + (9 * 4) = 9(3 + 4)

ur basically just factoring
