Which is the least common multiple in the world?
A Venn diagram showing the least common multiples of combinations of 2, 3, 4, 5 and 7 (6 is skipped as it is 2 × 3, both of which are already represented).
Which is the least common multiple of 4 and 6?
For example, the LCM of 4 and 6 is 12, which is represented by the green triangle (= 4) in the (5, 12) position. A Venn diagram showing the least common multiples of combinations of 2, 3, 4, 5 and 7 (6 is skipped as it is 2 × 3, both of which are already represented).
Which is the least common multiple of 5 and 2?
Because 10 is the smallest positive integer that is divisible by both 5 and 2, it is the least common multiple of 5 and 2. By the same principle, 10 is the least common multiple of −5 and −2 as well. The least common multiple of two integers a and b is denoted as lcm ( a, b ).
How to find the least common multiple for an integer?
How to find the Least Common Multiple. For integers a and b you can find the greatest common divisor (GCD) of a and b and use that result to calculate the least common multiple. You can also find the prime factorization of each integer and use those results to calculate the LCM. LCM(a,b) = (a*b)/GCD(a,b)
