    What's the Least Common Multiple (LCM) of 35, 60 and 100?

    Answer

    LCM of 35, 60 and 100 is
    2,100

    (Two thousand one hundred)

    2,100 is the smallest positive integer that 35, 60 and 100 all divide without a remainder — every other common multiple of the three is a multiple of it.

    Finding the LCM of 35, 60 and 100 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 35: 5 × 7 (exponent form: 5 × 7)

    All Prime Factors of 60: 2 × 2 × 3 × 5 (exponent form: 22 × 3 × 5)

    All Prime Factors of 100: 2 × 2 × 5 × 5 (exponent form: 22 × 52)

    LCM = 22 × 3 × 52 × 7 = 2,100

    Checking the LCM of 35, 60 and 100 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(35, 60) = (35 × 60) ÷ 5 = 2,100 ÷ 5 = 420

    LCM(420, 100) = (420 × 100) ÷ 20 = 42,000 ÷ 20 = 2,100

    LCM(35, 60, 100) = 2,100

    The pairs may be taken in any order — 60 and 100 first, then 35 — and the answer is the same 2,100. That is exactly why the two routes on this page agree.

    FAQ

    What's the Least Common Multiple (LCM) of 35, 60 and 100?

    LCM of 35, 60 and 100 is 2,100

    How to find the LCM of 35, 60 and 100 by prime factorization?

    Take every prime that appears in 35, 60 and 100 to the highest power it reaches in any one of them and multiply: 2² × 3 × 5² × 7 = 2,100.

    Can you get the LCM of 35, 60 and 100 two numbers at a time?

    Yes, and it is the check this page prints. The LCM of 35 and 60 is 420, and the LCM of 420 and 100 is 2,100 — the same answer, because the least common multiple is associative and does not depend on the order of the three numbers.

    Is 2,100 divisible by 35, 60 and 100?

    Yes, and by definition it is the smallest positive integer that is: 2,100 ÷ 35, 2,100 ÷ 60 and 2,100 ÷ 100 all come out whole. Any other common multiple of 35, 60 and 100 is a multiple of 2,100.
