40 = 2 * 2 * 2 * 5
The GCF of 2 and 40 is 2.
It is: 2*2*2*5 = 40
Because 40 can be divided by 2 with no remainder.
40 and 80
4
Common factors are those that can be divided into two different numbers. For 4 and 40, their common factors are: 1, 2, 4, -1, -2, -4. Of these, the largest number is 4 (and this is therefore the greatest common factor).
The greatest common factor of 14 and 40 is 2.The GCF of 14 and 40 is 2. This leaves you with 7 and 20, of which there are no further common factors aside from 1.The greatest common factor for the number 14 and 40 is 2.
