1, 2, 3 and 6
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The common factors are: 1, 2, 3, 6
The common factors are: 1, 2, 3, 6.
I belive that it is 6
The greatest common factor of 42 and 72 is 6 Gcf stands for Greatest Common Factor, The gcf of 42 and 72 is the largest positive number that is a factor of both 42 and 72. The positive factors of 42 (the integral divisors of 42) are: 1, 2, 3, 6, 7, 14, 21, and 42. The positive factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 36, and 72. Therefore the gcf of 42 and 72 is 6, as the greatest factor that 42 and 72 have in common.
1, 2, 3 and 6
Answer: 6Definition: 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.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 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.The common factors are 1, 2, 3, and 6. Therefore, the greatest common factor is 6.
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72GCF (30, 42, 72) = 6
The greatest common factor (GCF) of 24, 42, and 72 is 6.
The common factors of 72 and 123 are: 1 and 3
The common factors of 72 and 86 are: 1 and 2
The common factors of 21 and 42 are 1,3,7,21
The factors of 39 are: 1, 3, 13, 39 The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The common factors of 42 and 273 are 1, 3, 7 and 21.
