    What's the Least Common Multiple (LCM) of 20 and 190?

    Answer

    LCM of 20 and 190 is
    380

    (Three hundred eighty)

    Finding LCM for 20 and 190 using GCF of these numbers

    The first method to find LCM for numbers 20 and 190 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 20 and 190 is 10, so

    LCM = (20 × 190) ÷ 10

    LCM = 3800 ÷ 10

    LCM = 380

    Finding LCM for 20 and 190 by Listing Multiples

    The second method to find LCM for numbers 20 and 190 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

    Multiples of 190: 190, 380, 570, 760

    So the LCM for 20 and 190 is 380

    Finding LCM for 20 and 190 by Prime Factorization

    Another method to find LCM for numbers 20 and 190 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 190: 2, 5, 19 (exponent form: 21, 51, 191)

    22 × 51 × 191 = 380
