Answer: 3Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor 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 21 are 1, 3, 7, and 21.The factors of 27 are 1, 3, 9, and 27.The common factors are 1 and 3. Therefore, the greatest common factor is 3.
The factors of 21 are 1, 3, 7, and 21. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The common factors are 1 and 3. The greatest common factor is 3.
The factors of 12 are: 1, 2, 3, 4, 6, 12The factors of 15 are: 1, 3, 5, 15The factors of 21 are: 1, 3, 7, 21The common factors are: 1, 3The Greatest Common Factor (GCF) is: 3
The factors of 105 are 1, 3, 5, 7, 15, 21, 35, 10. For them to be common, they need to be compared to another set of factors.
