    What's the Least Common Multiple (LCM) of 3, 8 and 11?

    Answer

    LCM of 3, 8 and 11 is
    264

    (Two hundred sixty-four)

    264 is the smallest positive integer that 3, 8 and 11 all divide without a remainder — every other common multiple of the three is a multiple of it.

    Finding the LCM of 3, 8 and 11 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 3: 3 (exponent form: 3)

    All Prime Factors of 8: 2 × 2 × 2 (exponent form: 23)

    All Prime Factors of 11: 11 (exponent form: 11)

    2—23—23
    33——3
    11——1111

    LCM = 23 × 3 × 11 = 264

    Checking the LCM of 3, 8 and 11 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(3, 8) = (3 × 8) ÷ 1 = 24 ÷ 1 = 24

    LCM(24, 11) = (24 × 11) ÷ 1 = 264 ÷ 1 = 264

    LCM(3, 8, 11) = 264

    The pairs may be taken in any order — 8 and 11 first, then 3 — and the answer is the same 264. That is exactly why the two routes on this page agree.

    FAQ

    What's the Least Common Multiple (LCM) of 3, 8 and 11?

    LCM of 3, 8 and 11 is 264

    How to find the LCM of 3, 8 and 11 by prime factorization?

    Take every prime that appears in 3, 8 and 11 to the highest power it reaches in any one of them and multiply: 2³ × 3 × 11 = 264.

    Can you get the LCM of 3, 8 and 11 two numbers at a time?

    Yes, and it is the check this page prints. The LCM of 3 and 8 is 24, and the LCM of 24 and 11 is 264 — the same answer, because the least common multiple is associative and does not depend on the order of the three numbers.

    Is 264 divisible by 3, 8 and 11?

    Yes, and by definition it is the smallest positive integer that is: 264 ÷ 3, 264 ÷ 8 and 264 ÷ 11 all come out whole. Any other common multiple of 3, 8 and 11 is a multiple of 264.
