Best Answer

The greatest common factor of 40 and 80 is 40. (Whenever one of a pair of number is a factor of the other larger number, it is the GCF of the two.)

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.
The GCF is: 40

What is the HCF of 40 and 80?

The highest common factor is the greatest number which both numbers can divide by evenly. In this case, the greatest number 40 can divide by is 40. 80 can also divide by 40, and so this is a common factor. As no numbers greater than 40 will be able to divide 40 evenly, the hcf of 40 and 80 is 40.
