Because 4 is the largest number that will divide into both of those numbers evenly, with no remainder.
It is 4
The greatest common factor of 156 , 40 = 4
Since 40 is a factor of 280, it is automatically the GCF.
The GCF is... 1! 1 is the only factor common to all three numbers.
8
The greatest common factor of 1628 , 40 = 4
Greatest Common Factor (GCF) of (12,40,56) is 4.
It is 4
The GCF of 12 and 40 is 4.
4
It is 4
The GCF of 12 and 40 is 4.
1, 2, 4 are the common factors of 12 and 40, and 4 is the greatest common factor
it is 40 because it is the greatest common factor for the numbers10 and 40
It is: 4
There is none: 1.
8 is the greatest common factor for 48 and 40
