The only factor common to all three numbers is... 1
The common factors of 28 and 70 are:28 factors are 1, 2, 4, 7, 14, 2870 factors are 1, 2, 5, 7, 10, 14, 35, 70So the common factors are 1, 2, 7, and 14
The common factors of 140 and 210 are: 1, 2, 5, 7, 10, 14, 35, and 70
The factors of 21 are:1, 3, 7, 21The factors of 350 are:1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350The common factors are:1, 7
70 = 7 x 10 = 7 x 2 x 5 56 = 7 x 8 = 7 x 2 x 2 x 2 Common factors are 1, 2, 7 and 14
The factors of 10 are: 1, 2, 5, 10The factors of 14 are: 1, 2, 7, 14The common factors are: 1, 2The Greatest Common Factor (GCF) is: 2
The factors of 10 are 1, 2, 5, and 10. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The common factors of 10 and 70 are 1, 2, 5, and 10. Therefore, the least common factor (the smallest common factor) is 1.
Factors of 3: 1, 3.Factors of 7: 1, 7.Factors of 10: 1, 2, 5, 10.GCF (3, 7, 10) = 1
7 and 10 share no common factors aside from 1.
The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70The factors of 98 are: 1, 2, 7, 14, 49, 98The common factors are: 1, 2, 7, 14The Greatest Common Factor (GCF) is: 14
The greatest common factor of 70 and 100 is 10.The common factors of 70 and 100 are 1, 2, 5, and 10.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70.The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.The common factors are 1, 2, 5, and 10. Therefore, the greatest common factor is 10.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 70 are 2, 5, and 7.The prime factors of 100 are 2, 2, 5, and 5.The prime factors in common are 2 and 5, so the greatest common factor is 2 x 5 = 10.Still another way is to recognize that both numbers are divisible by 10 since they both end in 0. Then, divide both numbers by 10 and compare the results.70 ÷ 10 = 7100 ÷ 10 = 10Since 7 and 10 do not have any factors in common, the greatest common factor is 10.
The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70The factors of 20 are: 1, 2, 4, 5, 10, 20The common factors are: 1, 2, 5, 10
The factors of 50 are 1, 2, 5, 10, 25, and 50. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70.
