Answer: 4Definition: 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 28 are 1, 2, 4, 7, 14, and 28.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.The greatest common factor of the numbers 28 and 40 is 4.
The GCF is: 4
The GCF is 4.
Answer: 1 The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors are 1, 2, and 4; the least (smallest) common factor is 1.
The GCF is 4.
The common factors are: 1, 2, 4
