The factors of 12 are: 1, 2, 3, 4, 6, 12 The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30 The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42
the factors of 42 are 1,42,6,7,2,21,3,14
Factors of 42: 1 2 3 6 7 14 21 42 Factors of 60: 1 2 3 4 5 6 10 12 15 20 30 60 The GCF of 42 and 60 is 6
The factors of 42 are 1,2,3,6,7,14,21,42. The factors of 66 are 1,2,3,6,11,22,33,66
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
Factors of 15: 1, 3, 5, 15. Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42. GCF (15, 42) = 3
If the GCF of two numbers is 1 then the numbers are co-prime or a pair of numbers which have only 1 as their common factoris called co-prime.Let us check if 15 and 42 share any common factors other than 1.Factors of 15: 1, 3, 5 and 15.Factors of 42: 1, 2, 3, 6, 7, 21 and 42.As it can be seen that 3 is a common factor or GCF of 15 and 42.So, 15 and 42 are not co-prime.
