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.
