Prime factorization.
Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCM
The easiest way is to multiply the numbers together. The answer won't necessarily be the least common multiple, but it will be a common multiple. The easiest way to get a common multiple is to multiply the numbers together. The result will not necessarily be the least common multiple, but it will be a common multiple.
Since 36 is a multiple of 9, it has to be the LCM of the problem.
The least common multiple of 4 & 7???? so are you talking about the least common denominator? if so: I usually figure out the least common multiple of 2 numbers by just multiplying the two numbers together (IE. 7x11=77) but in your case it would be 4x7 so your answer is 28 Hope that helped!!!! Remember to show your work!!!
That's known as the least common multiple, or LCM.
Prime factors of 51 are 3 and 17 Prime factors of 34 are 2 and 17 Least common multiple is 2*3*17 = 102

The answer is 42 (easiest way to start is 2*3*7)The least common multiple of 2 , 3 , 7 = 42
The least common denominator is the least common multiple of the denominators.
The lowest common multiple of 6, 8, and 9 is impossible I tryed to figure that out for 20 minutes. It can't be done.
The least common multiple of 14 and 27 is 378
If the GCF of w and Y is 1, multiply them together.
