    What's the Least Common Multiple (LCM) of 10, 25 and 30?

    Answer

    LCM of 10, 25 and 30 is
    150

    (One hundred fifty)

    150 is the smallest positive integer that 10, 25 and 30 all divide without a remainder — every other common multiple of the three is a multiple of it.

    Finding the LCM of 10, 25 and 30 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 10: 2 × 5 (exponent form: 2 × 5)

    All Prime Factors of 25: 5 × 5 (exponent form: 52)

    All Prime Factors of 30: 2 × 3 × 5 (exponent form: 2 × 3 × 5)

    LCM = 2 × 3 × 52 = 150

    Checking the LCM of 10, 25 and 30 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(10, 25) = (10 × 25) ÷ 5 = 250 ÷ 5 = 50

    LCM(50, 30) = (50 × 30) ÷ 10 = 1,500 ÷ 10 = 150

    LCM(10, 25, 30) = 150

    The pairs may be taken in any order — 25 and 30 first, then 10 — and the answer is the same 150. That is exactly why the two routes on this page agree.

    FAQ

    What's the Least Common Multiple (LCM) of 10, 25 and 30?

    LCM of 10, 25 and 30 is 150

    How to find the LCM of 10, 25 and 30 by prime factorization?

    Take every prime that appears in 10, 25 and 30 to the highest power it reaches in any one of them and multiply: 2 × 3 × 5² = 150.

    Can you get the LCM of 10, 25 and 30 two numbers at a time?

    Yes, and it is the check this page prints. The LCM of 10 and 25 is 50, and the LCM of 50 and 30 is 150 — the same answer, because the least common multiple is associative and does not depend on the order of the three numbers.

    Is 150 divisible by 10, 25 and 30?

    Yes, and by definition it is the smallest positive integer that is: 150 ÷ 10, 150 ÷ 25 and 150 ÷ 30 all come out whole. Any other common multiple of 10, 25 and 30 is a multiple of 150.
