Best Answer

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

Yes, always. This is the easiest way to find the LCM of two (or indeed any number of) primes.

easiest way take 6 and go through its multiples until you find a number that is divisible by all four numbers, 6,12,18 etc in this case 60 is the answer

The easiest way is to write the number and a factor of the number. 12 and 24 have an LCM of 24.

Many people find factor trees to be the easiest.

A common denominator. The best way is to find the LCM (Lowest Common Multiple) of all the denominators - the smallest number into which all the denominators will divide. (The easiest way to do this is to multiply all the different denominators together. Once this common denominator has been found, convert all the fractions into equivalent fractions with this new denominator.
