    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

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

    Answer

    LCM of 18 and 54 is
    54

    (Fifty-four)

    Finding LCM for 18 and 54 using GCF of these numbers

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

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 18 and 54 is 18, so

    LCM = (18 × 54) ÷ 18

    LCM = 972 ÷ 18

    LCM = 54

    Finding LCM for 18 and 54 by Listing Multiples

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

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

    Multiples of 54: 54, 108, 162

    So the LCM for 18 and 54 is 54

    Finding LCM for 18 and 54 by Prime Factorization

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

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

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

    21 × 33 = 54
