    What's the Least Common Multiple (LCM) of 16, 24 and 32?

    Answer

    LCM of 16, 24 and 32 is
    96

    (Ninety-six)

    96 is the smallest positive integer that 16, 24 and 32 all divide without a remainder — every other common multiple of the three is a multiple of it.

    Finding the LCM of 16, 24 and 32 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 16: 2 × 2 × 2 × 2 (exponent form: 24)

    All Prime Factors of 24: 2 × 2 × 2 × 3 (exponent form: 23 × 3)

    All Prime Factors of 32: 2 × 2 × 2 × 2 × 2 (exponent form: 25)

    LCM = 25 × 3 = 96

    Checking the LCM of 16, 24 and 32 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(16, 24) = (16 × 24) ÷ 8 = 384 ÷ 8 = 48

    LCM(48, 32) = (48 × 32) ÷ 16 = 1,536 ÷ 16 = 96

    LCM(16, 24, 32) = 96

    The pairs may be taken in any order — 24 and 32 first, then 16 — and the answer is the same 96. That is exactly why the two routes on this page agree.

    FAQ

    What's the Least Common Multiple (LCM) of 16, 24 and 32?

    LCM of 16, 24 and 32 is 96

    How to find the LCM of 16, 24 and 32 by prime factorization?

    Take every prime that appears in 16, 24 and 32 to the highest power it reaches in any one of them and multiply: 2⁵ × 3 = 96.

    Can you get the LCM of 16, 24 and 32 two numbers at a time?

    Yes, and it is the check this page prints. The LCM of 16 and 24 is 48, and the LCM of 48 and 32 is 96 — the same answer, because the least common multiple is associative and does not depend on the order of the three numbers.

    Is 96 divisible by 16, 24 and 32?

    Yes, and by definition it is the smallest positive integer that is: 96 ÷ 16, 96 ÷ 24 and 96 ÷ 32 all come out whole. Any other common multiple of 16, 24 and 32 is a multiple of 96.
