What Is The GCF Of 24,40?

GCF is the abbreviation of Greatest Common Factor and it is the largest number that is the divisor of a set of numbers. The GCF can be found through the following process:
First of all find the factors of both the numbers:
24= 2 x 2 x 2 x 3
40= 2 x 2 x 2 x 5

The common factors are 2x2x2
Thus the GCF would be 8

Euclidean algorithm:
40 / 24 = (24 * 1) + 16

24 / 16 = (16 * 1) + 8

16 / 8 = (8 * 2) + 0

Since the last remainder is zero, the algorithm ends with 8 as the greatest common divisor of 24 and 40.
