25*3 is 75 and 25*4 is 100
So 25 is the gcf

75 branches into 25*3 which branches into 5*5*3
100 goes into 4*25 which is 4*5*5
completely factor the 2 numbers then multiply the numbers togther that both have in common
so the answer is 5*5=25 is your GCF

First we need to find all of the factors (what will divide into the numbers.
75:
1,3,5,15,25,75
100:
1,2,4,5,10,20,25,50,100
The biggest number in both lists is 25. Therefore the greatest common factor is 25.

you can do it like this
75, 100 | 5
15 , 20 | 5
3 , 4 | -> you cant divide this two numbers no mor so you stop
and result is 5*5=25
____________
another example:
12, 24, 16 | 2
6 , 12 , 8 | 2
3 , 6 , 4 | stop
result 2*2=4
