2 and three
1, 2, and 53, have their first common multiple of 106.
Find the LCM, then multiply it by 2 and 3.
22, 44, 66
2 is the only common multiple with those three numbers.
They are: 18, 36 and 54
The way to solve this is as follows:Find the least common multiple of the two numbers.Multiply this least common multiple by 2 and by 3, to get the next two common multiples.
Every multiple of 24 is a common multiple of 2, 6 & 8. Where did "three" come from?
the first 2 common multiple of 18 and 32 is 288 and 576
Any multiple of 6.
The first three common multiples of 6 and 8 are the first three multiples of the least common multiple of 6 and 8. 6 = 2 x 3 and 8 = 2 x 2 x 2. Therefore, the LCM of 6 and 8 is 2 x 2 x 2 x 3 or 24. The first three multiples of 24 are 24, 48 and 72.
Suggestion: Find the least common multiple using your favorite method (for example, prime factorization). Then multiply that by 1, by 2, and by 3, to get your answer.
