The greatest common factor of 154 , 480 = 2
The greatest common factor of 300 , 480 = 60
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 480, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. Examples: The common factors of 13 and 480 are only 1; the greatest common factor is 1. The common factors of 81 and 480 are 1 and 3; the greatest common factor is 3. The common factors of 158 and 480 are 1 and 2; the greatest common factor is 2. The common factors of 380 and 480 are 1, 2, 4, 5, 10, and 20; the greatest common factor is 20. The common factors of 480 and 492 are 1, 2, 3, 4, 6, and 12; the greatest common factor is 12.
The greatest common factor of 68 and 480 is 4.
The greatest common factor of 250 and 480 is 10.
The GCF of 90 and 480 is 30.
To get the Greates Common Factor (GCF) of 60 and 480 we need to factor each value first and then we choose all the copies of factors and multiply them:
20
30
The GCF is 160.
The GCF is 60.
It is: 16
