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
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.
A division ladder isn't necessary. Since 25 is a factor of 75, it is automatically the GCF of this problem.
The GCF of 14 and 35 is 7.
The GCF is 1.
GCF(24, 14, 35) = 1
The Greatest Common Factor of 14, 35, 42 is 7.
The GCF of 35, 84 and 56 is 7. This leaves a remainder of 5, 12 and 8. There is no further common factor other than 1 for the resulting numbers.
The GCF is 1.
The GCF is 7.
The GCF is 2.
The only common positive integer factor of 36, 14, and 35 is 1.
