What is the gcf of 36 and 14 and 35?

Answer 1

The factors of 14 are:

1, 2, 7, 14

The factors of 35 are:

1, 5, 7, 35

The factors of 54 are:

1, 2, 3, 6, 9, 18, 27, 54

The Greatest Common Factor (GCF) is:

1

Answer 2

To find the GCF of two or more numbers, you can list the factor pairs of each and then find the greatest factor that is common to all the numbers:

24:

1 x 24

2 x 12

3 x 8

4 x 6

14:

1 x 14

2 x 7

35:

1 x 35

5 x 7

There are no factors except for 1 that are common to all numbers, so 1 is the GCF.

Answer 3

A division ladder isn't necessary. Since 25 is a factor of 75, it is automatically the GCF of this problem.

Answer 4

The GCF of 14 and 35 is 7.

Answer 5

The GCF is 1.

Answer 6

GCF(24, 14, 35) = 1
