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 both numbers have in common.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 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The factors of 105 are 1, 3, 5, 7, 15, 21, 35, and 105.The common factors are 1, 3, 7, and 21. Therefore, the greatest common factor is 21.The GCF of 42 and 105 is 21
It is: 630 by finding the prime factors of the given numbers
