# GCD of 80 and 29

You have reached us maybe looking for answers to the questions like: GCD of 80 and 29 or what is the highest common factor (HCF) of 80 and 29?

## What is the GCF of 80 and 29?

The first step to find the gcf of 80 and 29 is to list the factors of each number. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80. The factors of 29 are 1 and 29. So, the **Greatest Common Factor** for these numbers is 1 because it divides all them without a remainder. Read more about Common Factors below.

To use the GCD / GCF / HCF Calculator below just enter a set of numbers separated by commas (,).

### GCF example:

The first step is to find all divisors of each number. For instance, let us find the gcf(80, 29).

In this case we have:

- The factors of 80 (all the whole numbers that can divide the number without a remainder) are 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80;
- The factors of 29 are 1 and 29.

The second step is to analyze which are the common divisors. It is not difficult to see that the 'Greatest Common Factor' or 'Divisor' for 80 and 29 is 1. The GCF is the largest common positive integer that divides all the numbers (80, 29) without a remainder.

The GCF is also known as:

- Greatest common divisor (gcd);
- Highest common factor (hcf);
- Greatest common measure (gcm), or
- Highest common divisor
