What is the least common multiple of 40 50 and 70?

Answer 1

To find the least common multiple (LCM) of 40, 50, and 70, we first need to find the prime factorization of each number. The prime factorization of 40 is 2^3 * 5, the prime factorization of 50 is 2 * 5^2, and the prime factorization of 70 is 2 * 5 * 7. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers. Therefore, the LCM of 40, 50, and 70 is 2^3 * 5^2 * 7 = 1400.

Answer 2

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 40, 50, and 70 is 1400.
