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.
As a product of its prime factors in exponents: 22*53 = 500
The greatest factor of 99 is itself, which is 99. The greatest factor of any integer is the integer itself.
Try a factor tree. 99 33,3 11,3,3 3 x 3 x 11 = 99
The GCF of 75 and 99 is 3.
99 33,3 11,3,3
99 33,3 11,3,3
99 9, 11 3, 3, 11
22 2,11
22 2,11
22 2 x 11 Both 2 and 11 are prime numbers, so the factor tree is finished.
99 3,33 3,3,11 3 x 3 x 11 = 99
The GCF is 11.
22 2,11
