The factors of 56 are:1, 2, 4, 7, 8, 14, 28, 56The factors of 63 are:1, 3, 7, 9, 21, 63The factors of 72 are:1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72The common factors are:1The Greatest Common Factor:GCF = 1
The common factors of 63 and 56 are: 1, 7
The factors of 63 are 1,3,7,9,21, and 63 The factors of 56 are 1,2,4,7,8,14,28 and 56. The factors that are shared are 1 and 7. So the common factors of 63 and 56 are 1 and 7.
The GCF is 9.
Since 21 is a factor of 63, all of its factors are common.
The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72 The factors of 63 are 1, 3, 7, 9, 21, and 63 The common factors of 72 and 63 are 1, 3, and 9
The GCF of 63 and 72 is 9.The factors of 63 are: 1, 3, 7, 9, 21, 63The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72The common factors are: 1, 3, 9The Greatest Common Factor (GCF) is: 9
The GCF is 9.
The highest common factor is 9
For 63: 3 and 7 For 72: 2 and 3
1,3,7,9,21,63 1,2,3,4,8,9,18,24,36,72 The factors in common are 1,3,9 The largest (greatest) common factor is 9
The LCM of 63 and 72 is 504.
The greatest common denominator of 63, 72 and 24 is 3.
Common factors of 10 and 63 are: 1.
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 GCF of 49, 63, and 72 is 1.
The common factors of 28 and 63 are: 1 and 7
