    and

    What's the Least Common Multiple (LCM) of 20 and 475?

    Answer

    LCM of 20 and 475 is
    1,900

    (One thousand nine hundred)

    Finding LCM for 20 and 475 using GCF of these numbers

    The first method to find LCM for numbers 20 and 475 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 20 and 475 is 5, so

    LCM = (20 × 475) ÷ 5

    LCM = 9,500 ÷ 5

    LCM = 1,900

    Finding LCM for 20 and 475 by Listing Multiples

    The second method to find LCM for numbers 20 and 475 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, 520, 540, 560, 580, 600, 620, 640, 660, 680, 700, 720, 740, 760, 780, 800, 820, 840, 860, 880, 900, 920, 940, 960, 980, 1000, 1020, 1040, 1060, 1080, 1100, 1120, 1140, 1160, 1180, 1200, 1220, 1240, 1260, 1280, 1300, 1320, 1340, 1360, 1380, 1400, 1420, 1440, 1460, 1480, 1500, 1520, 1540, 1560, 1580, 1600, 1620, 1640, 1660, 1680, 1700, 1720, 1740, 1760, 1780, 1800, 1820, 1840, 1860, 1880, 1900, 1920, 1940

    Multiples of 475: 475, 950, 1425, 1900, 2375, 2850

    So the LCM for 20 and 475 is 1,900

    Finding LCM for 20 and 475 by Prime Factorization

    Another method to find LCM for numbers 20 and 475 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 475: 5, 5, 19 (exponent form: 52, 191)

    22 × 52 × 191 = 1,900
