    What's the Least Common Multiple (LCM) of 90 and 285?

    Answer

    LCM of 90 and 285 is
    1,710

    (One thousand seven hundred ten)

    Finding LCM for 90 and 285 using GCF of these numbers

    The first method to find LCM for numbers 90 and 285 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 90 and 285 is 15, so

    LCM = (90 × 285) ÷ 15

    LCM = 25,650 ÷ 15

    LCM = 1,710

    Finding LCM for 90 and 285 by Listing Multiples

    The second method to find LCM for numbers 90 and 285 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, 1530, 1620, 1710, 1800, 1890

    Multiples of 285: 285, 570, 855, 1140, 1425, 1710, 1995, 2280

    So the LCM for 90 and 285 is 1,710

    Finding LCM for 90 and 285 by Prime Factorization

    Another method to find LCM for numbers 90 and 285 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 285: 3, 5, 19 (exponent form: 31, 51, 191)

    21 × 32 × 51 × 191 = 1,710
