Since 18 is a factor of 54, all of its factors are common.
The factors of 18 are 1, 2, 3, 6, 9, 18. For them to be common, they need to be compared to another set of factors.
2 and 3
The common factors of 12 and 18 are 1, 2, 3 and 6 To find the common factors, first list the factors of each number in the set. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 18 are 1, 2, 3, 6, 9, and 18. Next, note which factors are in both lists. In this case, the factors common to each list are 1, 2, 3, and 6. Thus, these are the common factor.
The factors of 18 are 1,2,3,6,9 and 18. For them to be common, they need to be compared to another set of factors.
