You need at least two numbers to find an LCM.

22 x 7 = 28

28 = 22 x 71

28 14,2 7,2,2

22 x 7 = 28

28 = 256

256 = 28

256 = 28.

No. The prime factorization of 28 is 2x2x7.

22 x 7 = 28

2 x 2 x 7 = 28 5 x 7 = 35 2 x 2 x 5 x 7 = 140, the LCM

22 x 71

It is: 4

The prime factorization of 256 is 28. The square root is 24 or 16.

It is: 2*2*7 = 28

768 = 28 x 31

It is: 2^2 times 7^1 = 28

The prime factorization is: 22 x 7

28 x 56 = 4,000,000

Since 58 is a multiple of 28, it is automatically the LCM, but if you insist... 2 x 2 x 7 = 28 2 x 2 x 2 x 7 = 56 2 x 2 x 2 x 7 = 56, the LCM

prime factorizations:2x2x7

2x2x7

28=2x2x7

2 x 5 = 10 2 x 2 x 7 = 28 Combine the factors, eliminating duplicates. 2 x 2 x 5 x 7 = 140, the LCM
