    What's the Least Common Multiple (LCM) of 24, 36 and 48?

    Answer

    LCM of 24, 36 and 48 is
    144

    (One hundred forty-four)

    144 is the smallest positive integer that 24, 36 and 48 all divide without a remainder — every other common multiple of the three is a multiple of it.

    Finding the LCM of 24, 36 and 48 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 24: 2 × 2 × 2 × 3 (exponent form: 23 × 3)

    All Prime Factors of 36: 2 × 2 × 3 × 3 (exponent form: 22 × 32)

    All Prime Factors of 48: 2 × 2 × 2 × 2 × 3 (exponent form: 24 × 3)

    LCM = 24 × 32 = 144

    Checking the LCM of 24, 36 and 48 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(24, 36) = (24 × 36) ÷ 12 = 864 ÷ 12 = 72

    LCM(72, 48) = (72 × 48) ÷ 24 = 3,456 ÷ 24 = 144

    LCM(24, 36, 48) = 144

    The pairs may be taken in any order — 36 and 48 first, then 24 — and the answer is the same 144. That is exactly why the two routes on this page agree.

    FAQ

    What's the Least Common Multiple (LCM) of 24, 36 and 48?

    LCM of 24, 36 and 48 is 144

    How to find the LCM of 24, 36 and 48 by prime factorization?

    Take every prime that appears in 24, 36 and 48 to the highest power it reaches in any one of them and multiply: 2⁴ × 3² = 144.

    Can you get the LCM of 24, 36 and 48 two numbers at a time?

    Yes, and it is the check this page prints. The LCM of 24 and 36 is 72, and the LCM of 72 and 48 is 144 — the same answer, because the least common multiple is associative and does not depend on the order of the three numbers.

    Is 144 divisible by 24, 36 and 48?

    Yes, and by definition it is the smallest positive integer that is: 144 ÷ 24, 144 ÷ 36 and 144 ÷ 48 all come out whole. Any other common multiple of 24, 36 and 48 is a multiple of 144.
