Question

What is the greatest common factors of 120 and 6

Answer 1

If we want to know the greatest common factor, we should ask: is one of the numbers divisible by the other? if yes, then the smaller number will be the answer!

let's try:

$\frac{120}{6} = \frac{60}{3} =20$

so, yes!
6 is the greatest common factor of the two:)
