The factors of 22 are 1, 2, 11, and 22.

The factors of 99 are 1, 3, 9, 11, 33, and 99.

The common factors are 1 and 11. Therefore, 11 is the greatest common factor.

The greatest common factor can also be determined from the prime factors by multiplying the common prime factors together.

The prime factors of 22 are 2 and 11.

The prime factors of 99 are 3, 3, and 11.

The common prime factors are a single 11, so the greatest common factor is 11.

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.
