Factors of 21: 1, 3, 7, and 21.Factors of 35: 1, 5, 7, and 35.You didn't ask for the factors that are common to 21 and 35.If you had asked for those, the answer would have been: 1 and 7 .
The factors of 21 are:1, 3, 7, 21The factors of 35 are:1, 5, 7, 35The common factors are:1, 7The Greatest Common Factor:GCF = 7
1 and 7
The GCF of 7, 21 and 35 is 7. This leaves you with 1, 3 and 5 respectively, You can go no further as the only common factor remaining is 1.The factors of 7 are: 1, 7The factors of 21 are: 1, 3, 7, 21The factors of 35 are: 1, 5, 7, 35The common factors are: 1, 7The Greatest Common Factor (GCF) is: 7
The GCF of 21 and 35 is 7.The factors of 21 are 1, 3, 7, and 21The factors of 35 are 1, 5, 7, and 35The greatest (largest) factor common to both 21 and 35 is 7The GCF is 7.
3 is a factor of 21, so ignore it. 21 factors to [3 7] 35 factors to [5 7] common factor [7] LCM = 21 * 35 / 7 = 105 ■
Factors of 21: 1, 3, 7, 21.Factors of 35: 1, 5, 7, 35.Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56.GCF (21, 35, 56) = 7
The factors of 21 are: 1, 3, 7, 21The factors of 35 are: 1, 5, 7, 35The common factors are: 1, 7
The GCF is 7.
