The factors of 32 are: 1, 2, 4, 8, 16, 32 The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56 The factors of 64 are: 1, 2, 4, 8, 16, 32, 64 The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The GCF of 56 and 72 is 8.The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72Thus, 8 is the GCF.
Break each number into its prime factors: 56 = 23 x 7 63 = 32 x 7 72 = 23 x 32 No prime factors are common to all three numbers, so we conclude that the GCF of the set is 1.
The least common multiple of 24 , 56 , 72 = 504
The GCF is 8.
56 = 23 × 7 196 = 22 × 72
The GCF is 8.
Common factors of 56 and 72 are 1, 2, 4 and 8.
1, 2, 4 and 8
The factors of 32 are: 1, 2, 4, 8, 16, 32 The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56 The factors of 64 are: 1, 2, 4, 8, 16, 32, 64 The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The GCF of 56 and 72 is 8.The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72Thus, 8 is the GCF.
the common factors are 2,4,8 and the greatest common factor is 8
It is: 56/72 = 7/9 by dividing 56 and 72 by their HCF
56+72=128
8 evenly divides all of the values, (3*8 = 24, 5*8 = 40, 7*8 = 56, 9*8 = 72), and, no other factors go into the numbers, thus 8 is the GCF.
The L.C.M. of 72 and 56 is 504
