You have reached us maybe looking for answers to the questions like: GCD of 1, 8 and 8 or what is the highest common factor (HCF) of 1, 8 and 8?

## What is the GCF of 1, 8 and 8?

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

## How to find the Greatest Common Factor

### GCF example:

The first step is to find all divisors of each number. For instance, let us find the gcf(1,8,8).

In this case we have:

• The factors of 1 (all the whole numbers that can divide the number without a remainder) are 1 and 1;
• The factors of 8 are 1, 2, 4 and 8;
• The factors of 8 are 1, 2, 4 and 8.

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 1, 8 and 8 is 1. The GCF is the largest common positive integer that divides all the numbers (1,8,8) 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
