# GCD of 7, 11 and 11

You have reached us maybe looking for answers to the questions like: GCD of 7, 11 and 11 or what is the highest common factor (HCF) of 7, 11 and 11?

## What is the GCF of 7, 11 and 11?

The first step to find the gcf of 7, 11 and 11 is to list the factors of each number. The factors of 7 are 1 and 7. The factors of 11 are 1 and 11. The factors of 11 are 1 and 11. 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(7,11,11).

In this case we have:

- The factors of 7 (all the whole numbers that can divide the number without a remainder) are 1 and 7;
- The factors of 11 are 1 and 11;
- The factors of 11 are 1 and 11.

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 7, 11 and 11 is 1. The GCF is the largest common positive integer that divides all the numbers (7,11,11) 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
