    "Least Common Multiple" Calculator
    Least Common Multiple of
    and

    What's the Least Common Multiple (LCM) of 20 and 46?

    Answer

    LCM of 20 and 46 is
    460

    (Four hundred sixty)

    Finding LCM for 20 and 46 using GCF of these numbers

    The first method to find LCM for numbers 20 and 46 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 20 and 46 is 2, so

    LCM = (20 × 46) ÷ 2

    LCM = 920 ÷ 2

    LCM = 460

    Finding LCM for 20 and 46 by Listing Multiples

    The second method to find LCM for numbers 20 and 46 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400, 420, 440, 460, 480, 500

    Multiples of 46: 46, 92, 138, 184, 230, 276, 322, 368, 414, 460, 506, 552

    So the LCM for 20 and 46 is 460

    Finding LCM for 20 and 46 by Prime Factorization

    Another method to find LCM for numbers 20 and 46 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 20: 2, 2, 5 (exponent form: 22, 51)

    All Prime Factors of 46: 2, 23 (exponent form: 21, 231)

    22 × 51 × 231 = 460
