    What's the Least Common Multiple (LCM) of 14 and 20?

    Answer

    LCM of 14 and 20 is
    140

    (One hundred forty)

    Finding LCM for 14 and 20 using GCF of these numbers

    The first method to find LCM for numbers 14 and 20 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 14 and 20 is 2, so

    LCM = (14 × 20) ÷ 2

    LCM = 280 ÷ 2

    LCM = 140

    Finding LCM for 14 and 20 by Listing Multiples

    The second method to find LCM for numbers 14 and 20 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 14: 14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 154, 168

    Multiples of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180

    So the LCM for 14 and 20 is 140

    Finding LCM for 14 and 20 by Prime Factorization

    Another method to find LCM for numbers 14 and 20 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 14: 2, 7 (exponent form: 21, 71)

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

    22 × 71 × 51 = 140
