What is the least common multiple of 49 and 343?

Answer 1

The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. In this case, the prime factorization of 49 is 7^2 and the prime factorization of 343 is 7^3. The LCM is found by taking the highest power of each prime factor that appears in either number, so the LCM of 49 and 343 is 7^3, which equals 343.

Answer 2

Short answer: There is none.

There is not a least common multiple of a single number, such as 23, because there cannot be any form of common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there is not a least common multiple.

Answer 3

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.

Since 343 is a single number, you could say that it shares all of its multiples with itself. So the least multiple of 343 is 343.

Answer 4

The Least Common Multiple (LCM) of (49,343) is 343.
