Question #45829

Answer 1

1. 3w
2. 6
3. 9

Explanation:

The GCD is the largest value that can be divided into each number and still result in a whole number. It can be found by separating out all of the prime number factors and then combining the similar ones.

1.`21w = 3 xx 7 xx w`
`18w = 3 xx 3 xx 2 xx w` ONLY one of the '3' and the 'w' are common: `3w`
The factored forms would be `7 and 6`

1. `6x = 3 xx 2 xx x`
   `12 = 3 xx 2 xx 2` The "3" and one "2" are common:
   `3 xx 2 = 6` The factored forms are `x and 2`.

2. `9g = 3 xx 3 xx g`
   `18h = 3 xx 3 xx 2 xx h` Two of the "3" are common:
   `3 xx 3 = 9` The factored forms are `g and 2h`.
