    What's the Least Common Multiple (LCM) of 35, 175 and 245?

    Answer

    LCM of 35, 175 and 245 is
    1,225

    (One thousand two hundred twenty-five)

    1,225 is the smallest positive integer that 35, 175 and 245 all divide without a remainder — every other common multiple of the three is a multiple of it.

    Finding the LCM of 35, 175 and 245 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 175: 5 × 5 × 7 (exponent form: 52 × 7)

    All Prime Factors of 245: 5 × 7 × 7 (exponent form: 5 × 72)

    LCM = 52 × 72 = 1,225

    Checking the LCM of 35, 175 and 245 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, 175) = (35 × 175) ÷ 35 = 6,125 ÷ 35 = 175

    LCM(175, 245) = (175 × 245) ÷ 35 = 42,875 ÷ 35 = 1,225

    LCM(35, 175, 245) = 1,225

    The pairs may be taken in any order — 175 and 245 first, then 35 — and the answer is the same 1,225. That is exactly why the two routes on this page agree.

    What's the Least Common Multiple (LCM) of 35, 175 and 245?

    LCM of 35, 175 and 245 is 1,225

    How to find the LCM of 35, 175 and 245 by prime factorization?

    Take every prime that appears in 35, 175 and 245 to the highest power it reaches in any one of them and multiply: 5² × 7² = 1,225.

    Can you get the LCM of 35, 175 and 245 two numbers at a time?

    Yes, and it is the check this page prints. The LCM of 35 and 175 is 175, and the LCM of 175 and 245 is 1,225 — the same answer, because the least common multiple is associative and does not depend on the order of the three numbers.
