    What's the Least Common Multiple (LCM) of 25, 30 and 35?

    Answer

    LCM of 25, 30 and 35 is
    1,050

    (One thousand fifty)

    1,050 is the smallest positive integer that 25, 30 and 35 all divide without a remainder — every other common multiple of the three is a multiple of it.

    Finding the LCM of 25, 30 and 35 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 25: 5 × 5 (exponent form: 52)

    All Prime Factors of 30: 2 × 3 × 5 (exponent form: 2 × 3 × 5)

    All Prime Factors of 35: 5 × 7 (exponent form: 5 × 7)

    LCM = 2 × 3 × 52 × 7 = 1,050

    Checking the LCM of 25, 30 and 35 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(25, 30) = (25 × 30) ÷ 5 = 750 ÷ 5 = 150

    LCM(150, 35) = (150 × 35) ÷ 5 = 5,250 ÷ 5 = 1,050

    LCM(25, 30, 35) = 1,050

    The pairs may be taken in any order — 30 and 35 first, then 25 — and the answer is the same 1,050. That is exactly why the two routes on this page agree.

    FAQ

    What's the Least Common Multiple (LCM) of 25, 30 and 35?

    LCM of 25, 30 and 35 is 1,050

    How to find the LCM of 25, 30 and 35 by prime factorization?

    Take every prime that appears in 25, 30 and 35 to the highest power it reaches in any one of them and multiply: 2 × 3 × 5² × 7 = 1,050.

    Can you get the LCM of 25, 30 and 35 two numbers at a time?

    Yes, and it is the check this page prints. The LCM of 25 and 30 is 150, and the LCM of 150 and 35 is 1,050 — the same answer, because the least common multiple is associative and does not depend on the order of the three numbers.

    Is 1,050 divisible by 25, 30 and 35?

    Yes, and by definition it is the smallest positive integer that is: 1,050 ÷ 25, 1,050 ÷ 30 and 1,050 ÷ 35 all come out whole. Any other common multiple of 25, 30 and 35 is a multiple of 1,050.
