    What's the Least Common Multiple (LCM) of 50, 100 and 500?

    Answer

    LCM of 50, 100 and 500 is
    500

    (Five hundred)

    500 is the smallest positive integer that 50, 100 and 500 all divide without a remainder — every other common multiple of the three is a multiple of it.

    Finding the LCM of 50, 100 and 500 by Prime Factorization

    Split all three numbers into prime factors, then take every prime that shows up in at least one of them, each raised to the highest power it reaches there. Multiplying those highest powers gives the least common multiple:

    All Prime Factors of 50: 2 × 5 × 5 (exponent form: 2 × 52)

    All Prime Factors of 100: 2 × 2 × 5 × 5 (exponent form: 22 × 52)

    All Prime Factors of 500: 2 × 2 × 5 × 5 × 5 (exponent form: 22 × 53)

    LCM = 22 × 53 = 500

    Checking the LCM of 50, 100 and 500 Two Numbers at a Time

    The least common multiple is associative, so three numbers can be handled as two pairs: first the LCM of the first two, then the LCM of that value and the third. Each pair goes through the two-number formula, which uses the greatest common divisor:

    LCM(a, b) = (a × b) ÷ GCD(a, b)

    LCM(50, 100) = (50 × 100) ÷ 50 = 5,000 ÷ 50 = 100

    LCM(100, 500) = (100 × 500) ÷ 100 = 50,000 ÷ 100 = 500

    LCM(50, 100, 500) = 500

    The pairs may be taken in any order — 100 and 500 first, then 50 — and the answer is the same 500. That is exactly why the two routes on this page agree.

    FAQ

    What's the Least Common Multiple (LCM) of 50, 100 and 500?

    LCM of 50, 100 and 500 is 500

    How to find the LCM of 50, 100 and 500 by prime factorization?

    Take every prime that appears in 50, 100 and 500 to the highest power it reaches in any one of them and multiply: 2² × 5³ = 500.

    Can you get the LCM of 50, 100 and 500 two numbers at a time?

    Yes, and it is the check this page prints. The LCM of 50 and 100 is 100, and the LCM of 100 and 500 is 500 — the same answer, because the least common multiple is associative and does not depend on the order of the three numbers.

    Is 500 divisible by 50, 100 and 500?

    Yes, and by definition it is the smallest positive integer that is: 500 ÷ 50, 500 ÷ 100 and 500 ÷ 500 all come out whole. Any other common multiple of 50, 100 and 500 is a multiple of 500.
