There are no common factors of 15 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common.The factors of 15 are 1, 3, 5, and 15.Examples:The common factors of 6 and 15 are 1 and 3.The common factors of 15 and 90 are 1, 3, 5, and 15.1,5,3, and 15.
The factors of 3 are: 1 and 3The factors of 4 are: 1, 2, and 4None of the factors of 3 or 4 are between 15 and 45.
Common factors of 105, 165, and 30 are: 1, 3, 5, and 15.
The idea is to look for common factors, between the 15 and the 100. Then, divide both numbers by this common factor.
Since 15 is a factor of 45, its factors are the common factors of 15 and 45. The factors of 15 are 1, 3, 5, and 15. The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors they have in common are 1, 3, 5, and 15.
