The factors of 40 are 1,2,4,5,8,10,20 and 40. For them to be common, they need to be compared to another set of factors.
Since 20 is a factor of 40, all of its factors are common.
Since 40 is a factor of 120, all of its factors are common.
Common factors of 36 and 40 are: 1, 2, and 4.
Common factors of 24 and 40 are: 1, 2, 4, and 8.
Since 40 is a factor of 80, all of its factors are common.
Since 8 is a factor of 40, it is automatically the GCF and all of its factors are common.
The common factors are: 1, 2, 4.
The common factors for the numbers 25 95 and 40 are: 1, 5
The common factors are: 1, 2, 4, 8
All the factors of 12 are 1,2,3,4,6,12All the factors of 40 are 1,2,4,5,8,10,20,40The common factors are 1,2,4Common factors of 12 and 40 are: 1, 2, and 4.1, 2 and 4
One way to determine the common factors 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 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors are 1 and 5. The greatest common factor is 5.
