What are all the greatest common factors of 14 and 56?
The GCF of 14, 31, 39, and 56 is 1. One way to solve the problem is to notice that 31 is prime, and can't possibly be a factor of 14, which is smaller.If you prefer, you can write the prime factorization of each number in the set and find the GCF:The prime factorization of 14 is 2*7The prime factorization of 31 is 31 (1*31)The prime factorization of 39 is 3*39The prime factorization of 56 is 2*2*2*7So the GCF is 1.
What is the prime factorization of 71421 use the prime factors what is the LCM and CF of each number?
You can't find an LCM or a CF of a single number. You need at least two. The prime factorization of 71421 is 3 x 7 x 19 x 179 If you're asking about 7, 14 and 21, the LCM is 42 and the CF are 1 and 7 7 2 x 7 3 x 7
What is the LCM of 14 27 and 30 using the group factoring method?
The LCM is 1,890
If you do the LCM of 14 21 and 28 by listing all the factor's you get 84 but if you do prime factorization it comes out 168 Why?
2 x 7 = 14 3 x 7 = 21 2 x 2 x 7 = 28 2 x 2 x 3 x 7 = 84, the LCM If you got 168, you didn't eliminate the 2 from 14.
What is the LCM for 14 and 7?
The Least Common Multiple (LCM) of 7 and 14 is 14.
