The GCF of 20 and 40 is 20
The GCF of 15 and 30 is 15
The GCF of 15, 20, 30 and 40 is 5.
The greatest common factor of 28 and 20 is 4.
The Greatest Common Factor (GCF) is: 4
The greatest common factor of 2,040 and 1,100 is: 20.
One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 15 are 1, 3, 5, and 15.The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.The common factors are 1 and 5. Therefore, the greatest common factor is 5.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 15 are 3 and 5.The prime factors of 100 are 2, 2, 5, and 5.The prime factors in common are 5, so the greatest common factor is 5.ANSWER: 5The GCF is 5.

The greatest common factor of 120 and 245 is 5.
The greatest common factor of 10, 15, and 20 is 5.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 10 are 1, 2, 5, and 10.The factors of 15 are 1, 3, 5, and 15.The factors of 20 are 1, 2, 4, 5, 10, and 20.The common factors are 1 and 5. Therefore, the greatest common factor is 5.If you mean: 10, 15 and 20 then it is 5 that is the greatest common factor
The GCF is 1.
