    What's the Least Common Multiple (LCM) of 54 and 18?

    Answer

    LCM of 54 and 18 is
    54

    (Fifty-four)

    Finding LCM for 54 and 18 using GCF of these numbers

    The first method to find LCM for numbers 54 and 18 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 54 and 18 is 18, so

    LCM = (54 × 18) ÷ 18

    LCM = 972 ÷ 18

    LCM = 54

    Finding LCM for 54 and 18 by Listing Multiples

    The second method to find LCM for numbers 54 and 18 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 54: 54, 108, 162

    Multiples of 18: 18, 36, 54, 72, 90

    So the LCM for 54 and 18 is 54

    Finding LCM for 54 and 18 by Prime Factorization

    Another method to find LCM for numbers 54 and 18 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 54: 2, 3, 3, 3 (exponent form: 21, 33)

    All Prime Factors of 18: 2, 3, 3 (exponent form: 21, 32)

    21 × 33 = 54
