1, 2, 3, 6, 7, 14, 21, 42 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60The common factors of 42 and 60 are 1, 2, 3 and 66 is the GCF420 is the LCM
The common factors of 42 and 60 are: 1, 2, 3, and 6
The GCF of 42, 30, and 60 is 6.
60 - (30%) = 42
It has all the factors of 42 on one side and the factors of 60 in the other part with factors for both in the middle.
42
The GCF of 8, 42, and 60 is 2. The factors of 8 are 1, 2, 4, and 8. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The greatest common factor is 2. Or, you can look at the prime factors. The prime factors of 8 are 2, 2, and 2. The prime factors of 42 are 2, 3, and 7. The prime factors of 60 are 2, 3, and 5. The only prime factor they all have in common is 2, so the greatest common factor is 2. Using factor trees: 8 4,2 2,2,2 42 21,2 7,3,2 60 30,2 15,2,2 5,3,2,2 The GCF is 2.
70 % of 60 is 42
Factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.1 + 20 + 30 = 51
Since 30 is a factor of 60, all the factors of 30 will be common to 60.
