    What's the Least Common Multiple (LCM) of 42 and 48?

    Answer

    LCM of 42 and 48 is
    336

    (Three hundred thirty-six)

    Finding LCM for 42 and 48 using GCF of these numbers

    The first method to find LCM for numbers 42 and 48 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 42 and 48 is 6, so

    LCM = (42 × 48) ÷ 6

    LCM = 2016 ÷ 6

    LCM = 336

    Finding LCM for 42 and 48 by Listing Multiples

    The second method to find LCM for numbers 42 and 48 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 42: 42, 84, 126, 168, 210, 252, 294, 336, 378, 420

    Multiples of 48: 48, 96, 144, 192, 240, 288, 336, 384, 432

    So the LCM for 42 and 48 is 336

    Finding LCM for 42 and 48 by Prime Factorization

    Another method to find LCM for numbers 42 and 48 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 42: 2, 3, 7 (exponent form: 21, 31, 71)

    All Prime Factors of 48: 2, 2, 2, 2, 3 (exponent form: 24, 31)

    24 × 31 × 71 = 336
