    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 90 and 140?

    Answer

    LCM of 90 and 140 is
    1,260

    (One thousand two hundred sixty)

    Finding LCM for 90 and 140 using GCF of these numbers

    The first method to find LCM for numbers 90 and 140 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 90 and 140 is 10, so

    LCM = (90 × 140) ÷ 10

    LCM = 12600 ÷ 10

    LCM = 1260

    Finding LCM for 90 and 140 by Listing Multiples

    The second method to find LCM for numbers 90 and 140 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 90: 90, 180, 270, 360, 450, 540, 630, 720, 810, 900, 990, 1080, 1170, 1260, 1350, 1440

    Multiples of 140: 140, 280, 420, 560, 700, 840, 980, 1120, 1260, 1400, 1540

    So the LCM for 90 and 140 is 1260

    Finding LCM for 90 and 140 by Prime Factorization

    Another method to find LCM for numbers 90 and 140 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 90: 2, 3, 3, 5 (exponent form: 21, 32, 51)

    All Prime Factors of 140: 2, 2, 5, 7 (exponent form: 22, 51, 71)

    22 × 32 × 51 × 71 = 1260
