The factors of 18 are:1, 2, 3, 6, 9, 18The factors of 24 are:1, 2, 3, 4, 6, 8, 12, 24The factors of 36 are:1, 2, 3, 4, 6, 9, 12, 18, 36The common factors are:1, 2, 3, 6The Greatest Common Factor:GCF = 6
The greatest common factor for 12, 18, and 30 is 6. The factors of 12 are 1, 2, 3, 4, 6, and 12 The factors of 18 are 1, 2, 3, 6, 9, and 18 The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30 Thus, GCF (12, 18, 30) = 6
The Greatest Common Factor depends upon the numbers for which there are common factors and it is the greatest one of them; it can be greater than 18, for example the greatest common factor of 40 and 100 is 20. The greatest common factor must be one of the factors of each of the numbers. As the factors of each number cannot be greater than that number, the greatest common factor of a set of numbers cannot be greater than the least number. If this number is not greater than 18 then the greatest common factor of the numbers cannot be greater than 18. Even if the least number is greater than 18 it is possible that the greatest common factor of a set of numbers is still not greater than 18, for example the greatest common factor of 20, 30 and 50 is 10.
Common factors of 12, 15, and 18 are: 1 and 3.
The Greatest Common Factor (GCF) is: 9
