    What's the Least Common Multiple (LCM) of 84 and 420?

    Answer

    LCM of 84 and 420 is
    420

    (Four hundred twenty)

    Finding LCM for 84 and 420 using GCF of these numbers

    The first method to find LCM for numbers 84 and 420 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 84 and 420 is 84, so

    LCM = (84 × 420) ÷ 84

    LCM = 35,280 ÷ 84

    LCM = 420

    Finding LCM for 84 and 420 by Listing Multiples

    The second method to find LCM for numbers 84 and 420 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 84: 84, 168, 252, 336, 420, 504, 588

    Multiples of 420: 420, 840, 1,260

    So the LCM for 84 and 420 is 420

    Finding LCM for 84 and 420 by Prime Factorization

    Another method to find LCM for numbers 84 and 420 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 84: 2, 2, 3, 7 (exponent form: 22, 31, 71)

    All Prime Factors of 420: 2, 2, 3, 5, 7 (exponent form: 22, 31, 51, 71)

    22 × 31 × 71 × 51 = 420
