Using prime factors,
14 = 2 x 7
40 = 2^3 x 5
58 = 2 x 29.
So lcm(14,40,58) = 2^3 x 5 x 7 x 29 = 8120.
The Least Common Multiple (LCM) for 14 20 40 is 280.

The Least Common Multiple (LCM) for 40 49 is 1,960.
The Least Common Multiple (LCM) for 5 40 is 40.
Least common multiple of 5 10 and 40 is 40.
The least common multiple of 43 , 40 = 1,720
The least common multiple of 4, 5, and 8 is 40.
The least common multiple of 8 and 40 is 40. Because 40 is a multiple of 8, it is automatically the LCM of the set.
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) for 35 and 40 is 280
The Least Common Multiple (LCM) of 40 and 130 is 520.
The least common multiple of the numbers 40 and 12 is 120.
