To determine the least common multiple of two numbers, determine the prime factors of both number. Then, determine the prime factors they have in common. Multiply all their prime factors together and then divide by the prime factors they have in common.
The prime factors of 14 are 2 and 7.
The prime factors of 40 are 2, 2, 2, and 5.
The common prime factors are a single 2.
Therefore, the least common multiple is 2 x 7 x 2 x 2 x 2 x 5 ÷ 2 = 7 x 2 x 2 x 2 x 5 = 280.

The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.
The least common multiple of 14 and 44 is 308.
least common multiple of 2 and 40 = 40
Prime Factorization of:
2 = 2
40= 2 * 2 * 2 * 5
============
LCM=2 * 2 * 2 * 5 = 40
The LCM of 2 and 14 = 14
Multiples of 2: 2, 4, 6, 8, 10, 12, 14
Multiples of 14: 14, 28
The least common multiple, or LCM, is 40, since 40 is a multiple of 4 and of itself.
The Least Common Multiple of 47 and 41 and is 1,927.
The least common multiple of 41 , 18 = 738
The Least Common Multiple (LCM) for 23 41 is 943.
The least common multiple of 43 , 41 = 1,763
The least common multiple of the numbers 36, 18 and 41 is 1,476.
