Find Least Common Multiple of 2, 4 and 11 by listing out the factors.
Answer
LCM( 2, 4, 11 ) = 44
Explanation
Write down multiples of each number until you find the first common multiple:
The multipliers of 2 are: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, . . .
The multipliers of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, . . .
The multipliers of 11 are: 11, 22, 33, 44, 55, . . .
We can see that:
LCM( 2, 4, 11 ) = 44
This solution can be visualized using a Venn diagram.
