The factor pairs of 72 are: 1,72 and 2,36 and 3,24 and 4,18 and 6,12 and 8,9.

The factor pairs of 72 are (72,1), (36,2), (24,3), (18,4), (12,6), and (9,8).

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.

The greatest common factor (GCF) of 24, 42, and 72 is 6.

There are 4 factor pairs of 42.42 = 1 x 4242 = 2 x 2142 = 3 x 1442 = 6 x 7

The greatest common factor of 39, 42, and 72 is 3

The Greatest Common Factor of 42, 72 and 84 is 6.

the gcf ( greatest common factor ) of 42 , 72 , and 84 is 6 .

Factor pairs of 42 are 1 x 42, 2 x 21, 3 x 14, and 6 x 7.

The least common factor of any set of integers is 1.

GCF(36, 42, 72) = 6

Four of them.

60, 72, 84, 90 and 96 have 6 factor pairs.

The factor pairs of 72 are: 1 X 72 2 X 36 3 X 24 4 X 18 6 X 12 8 X 9

It is: 6

6

The GCF is 6.

The Least Common Multiple of two numbers is equal to their product divided by their greatest common factor.The greatest common factor of 72 and 42 is 6, so their Least Common Multiple is 72 * 42 / 6 = 504.

(42,1)(21,2)(14,3)(7,6)

(21,1)(7,3) (42,1)(21,2)(14,3)(7,6) Since 21 is a factor of 42, all the factors of 21 will be included in the factor pairs of 42.

factor pair = 42,1factor pair = 21,2factor pair = 14,3factor pair = 7,6
