A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.
One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.
The factors of 18 are 1, 2, 3, 6, 9, and 18.
The factors of 68 are 1, 2, 4, 17, 34, and 68.
The factors of 85 are 1, 5, 17, and 85.
The only common factor is 1. Therefore, the greatest common factor is 1.
The GCF of 18 and 68 is 2.The GCF is 2.
The greatest common factor of 12 and 68 is 4
The greatest common factor of 68 and 120 is 4.
The Greatest Common Factor (GCF) of 8 and 68 is: 4
The Greatest Common Factor of 24, 52, 68: 4
The GCF is 1.
The greatest common factor of 48 and 68 is 4
The greatest common factor of 60 and 68 is 4.
The greatest common factor of the numbers 17, 68 and 34 is 17.
The greatest common factor of 16 and 68 is 4. Factors of 16: 1,2,4,8,16. Factors of 68: 1,2,4,17,34,68.
The greatest common factor of 68 and 480 is 4.
The greatest common factor (GCF) is: 17
