    What's the Least Common Multiple (LCM) of 6, 10 and 14?

    Answer

    LCM of 6, 10 and 14 is
    210

    (Two hundred ten)

    210 is the smallest positive integer that 6, 10 and 14 all divide without a remainder — every other common multiple of the three is a multiple of it.

    Finding the LCM of 6, 10 and 14 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 6: 2 × 3 (exponent form: 2 × 3)

    All Prime Factors of 10: 2 × 5 (exponent form: 2 × 5)

    All Prime Factors of 14: 2 × 7 (exponent form: 2 × 7)

    LCM = 2 × 3 × 5 × 7 = 210

    Checking the LCM of 6, 10 and 14 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(6, 10) = (6 × 10) ÷ 2 = 60 ÷ 2 = 30

    LCM(30, 14) = (30 × 14) ÷ 2 = 420 ÷ 2 = 210

    LCM(6, 10, 14) = 210

    The pairs may be taken in any order — 10 and 14 first, then 6 — and the answer is the same 210. That is exactly why the two routes on this page agree.

    FAQ

    What's the Least Common Multiple (LCM) of 6, 10 and 14?

    LCM of 6, 10 and 14 is 210

    How to find the LCM of 6, 10 and 14 by prime factorization?

    Take every prime that appears in 6, 10 and 14 to the highest power it reaches in any one of them and multiply: 2 × 3 × 5 × 7 = 210.

    Can you get the LCM of 6, 10 and 14 two numbers at a time?

    Yes, and it is the check this page prints. The LCM of 6 and 10 is 30, and the LCM of 30 and 14 is 210 — the same answer, because the least common multiple is associative and does not depend on the order of the three numbers.

    Is 210 divisible by 6, 10 and 14?

    Yes, and by definition it is the smallest positive integer that is: 210 ÷ 6, 210 ÷ 10 and 210 ÷ 14 all come out whole. Any other common multiple of 6, 10 and 14 is a multiple of 210.
