The GCF of 60, 70, and 80 is 10. 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 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The common factors are 1, 2, 5, and 10. Therefore, the greatest common factor is 10.
The factors of 21 are 1,3,7, and 21. The factors of 70 are 1,2,5,7,14,35, and 70 The common factors of 21 and 70 are 1 and 7.
Prime factors of 60 are: 2, 3 and 5 Prime factors of 70 are: 2, 5 and 7
Greatest common factors of 7 42 & 70 is 7.
Factors of 50: 1 2 5 10 25 50. Prime factors are: 2 x 5 x 5 Factors of 60: 1 2 3 4 5 6 10 12 15 20 30 60. Prime factors are: 2 x 2 x 3 x 5 The prime Factors of 70: 1 2 5 7 10 14 35 70. Prime factors are: 2 x 5 x 7 The GCF of 50, 60, and 70 is 10 LCM is the multiple of the highest power of prime factors in two or more numbers. The LCM of 50, 60, and 70 is 2100, which is the multiple of the highest power of their prime factors (22 x 3 x 52 x 7).
60 and 70 have 4 common factors (divisors): 1; 2; 5 and 10
Common factors of 60 and 70 are: 1, 2, 5, and 10.
The GCF of 60, 70, and 80 is 10. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.
