What is the greatest common Factor of 40 and 5?

Answer 1

5 is a factor of 40, and 5 is the largest factor of itself, so the greatest common factor is 5.

The greatest common factor (GCF) is the highest number that divides exactly into two or more numbers without leaving a remainder. Factors are numbers you can multiply together to get another number. Since you can cleanly divide 40 by 5, and 5 can be divided by itself, the GCF of 5 and 40 is the number 5.

Answer 2

40 = 2 x 2 x 2 x 5

5 = 5

GFC = 5

Answer 3

The GCF is 5.
