1 and 7
The common factors of 28 and 63 are: 1 and 7
The common factors of 21 and 63 are 1, 3, 7, and 21
The common factors of 21 and 63 are: 1, 3, 7, and 21
The common factors of 21 and 63 are: 1, 3, 7, and 21.
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56 The factors of 63 are: 1, 3, 7, 9, 21, 63
The factors of 28 are: 1, 2, 4, 7, 14, 28 The factors of 63 are: 1, 3, 7, 9, 21, 63
To find the greatest common factor (GCF) of 28, 42, and 63, we first need to find the factors of each number. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 63 are 1, 3, 7, 9, 21, and 63. The GCF of 28, 42, and 63 is the largest number that appears in the factor lists of all three numbers, which is 7.
The common factors of 63 and 84 are: 1, 3, 7, and 21
The greatest common factor of 63 and 147 is 21.
The factors of 28 are:1, 2, 4, 7, 14, 28The factors of 189 are:1, 3, 7, 9, 21, 27, 63, 189The common factors are: 1, 7
The factors of 63 are 1, 3, 7, 9, 21 and 63. For them to be common, they need to be compared to another set of factors.
The greatest common factor (GCF) of two numbers is the largest number that divides evenly into both numbers. To find the GCF of 28 and 63, we need to list the factors of each number. The factors of 28 are 1, 2, 4, 7, 14, and 28, while the factors of 63 are 1, 3, 7, 9, 21, and 63. The largest number that appears in both lists is 7, so the GCF of 28 and 63 is 7.
