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 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
The factors of 45 are 1, 3, 5, 9, 15, and 45.
The factors of 50 are 1, 2, 5, 10, 25, and 50.
The common factors are 1 and 5. Therefore, the greatest common factor is 5.
The greatest common factor of 90 , 30 , 45 = 15
The Greatest Common Factor (GCF) is: 5
15 and 15000 have a greatest common factor of 15
The GCF is 5.
