The factors of 63 are 7*3*3 (or 7^1 * 3^2) The factors of 49 are 7*7 (or 7^2) When finding the GCF, you can use the highest power of a common factor. Is this case, the highest common factor is (7^1) since 63 only has a 7^1 The answer is 7.
Write down the factors of each number. Hence 3 = 1,3 4 = 1,2,2,4 5 = 1, 5, 6 = 1,2,3,6 7 = 1, 7 Hence 1, is common to all number. 2, is common to two numbers 3, is common to two numbers 5 is common to one number 7 is common to one number. Hence 1 x 2 x 3 x 5 x 7 = 210 the LCM.
The Greatest Common Factor (GCF) for 3, 7, 8 is 1 3 = 1, 3 7 = 1, 7 8 = 1, 2, 4, 8
1/7 + 2/3 (the common denominator is 21)= (1 x 3)/(7 x 3) + (2 x 7)/(3 x 7)= 3/21 + 14/21= (3 + 14)/21= 17/21, which is in its simplest form since both the numerator and the denominator do not have other common factors than 1.

42 - 1, 2, 3, 6, 7, 14, 21, 42 7 - 1, 7 the common factors are 1 and 7
Write down the factors of each number. Hence 3 = 1,3 4 = 1,2,2,4 5 = 1, 5, 6 = 1,2,3,6 7 = 1, 7 Hence 1, is common to all number. 2, is common to two numbers 3, is common to two numbers 5 is common to one number 7 is common to one number. Hence 1 x 2 x 3 x 5 x 7 = 210 the LCM.
The factors of 21 are: 1, 3, 7, 21.The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.The common factors are: 1, 3, 7, 21
The factors of 28 are: 1, 2, 4, 7, 14, 28.The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42.The common factors are: 1, 2, 7, 14
The Greatest Common Factor (GCF) for 3, 7, 8 is 1 3 = 1, 3 7 = 1, 7 8 = 1, 2, 4, 8
The common factors of 14 and 24 are: 1 and 2The factors of 14 are: 1, 2, 7, 14The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24The common factors are: 1, 2
The factors of 6 are 1, 2, 3, and 6. The factors of 21 are 1, 3, 7, and 21. The common factors of 6 and 21 are 1 and 3, and the GCF is 3.
The greatest common factor of 144 and 175 is 1. Factoring completely, we determine: 144 = 12 * 12 = 3 * 3 * 4 * 4 = 3 * 3 * 2 * 2 * 2 * 2 * 1 175 = 7 * 25 = 7 * 5 * 5 * 1 Since the only factor these have in common is 1, 1 is their greatest common factor.
[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7
2, 3, 4, 5, and 7 share no common factors aside from 1.
