    What's the Least Common Multiple (LCM) of 108, 120 and 132?

    Answer

    LCM of 108, 120 and 132 is
    11,880

    (Eleven thousand eight hundred eighty)

    11,880 is the smallest positive integer that 108, 120 and 132 all divide without a remainder — every other common multiple of the three is a multiple of it.

    Finding the LCM of 108, 120 and 132 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 108: 2 × 2 × 3 × 3 × 3 (exponent form: 22 × 33)

    All Prime Factors of 120: 2 × 2 × 2 × 3 × 5 (exponent form: 23 × 3 × 5)

    All Prime Factors of 132: 2 × 2 × 3 × 11 (exponent form: 22 × 3 × 11)

    LCM = 23 × 33 × 5 × 11 = 11,880

    Checking the LCM of 108, 120 and 132 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(108, 120) = (108 × 120) ÷ 12 = 12,960 ÷ 12 = 1,080

    LCM(1,080, 132) = (1,080 × 132) ÷ 12 = 142,560 ÷ 12 = 11,880

    LCM(108, 120, 132) = 11,880

    The pairs may be taken in any order — 120 and 132 first, then 108 — and the answer is the same 11,880. That is exactly why the two routes on this page agree.

    FAQ

    What's the Least Common Multiple (LCM) of 108, 120 and 132?

    LCM of 108, 120 and 132 is 11,880

    How to find the LCM of 108, 120 and 132 by prime factorization?

    Take every prime that appears in 108, 120 and 132 to the highest power it reaches in any one of them and multiply: 2³ × 3³ × 5 × 11 = 11,880.

    Can you get the LCM of 108, 120 and 132 two numbers at a time?

    Yes, and it is the check this page prints. The LCM of 108 and 120 is 1,080, and the LCM of 1,080 and 132 is 11,880 — the same answer, because the least common multiple is associative and does not depend on the order of the three numbers.
