    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 54 and 90?

    Answer

    LCM of 54 and 90 is
    270

    (Two hundred seventy)

    Finding LCM for 54 and 90 using GCF of these numbers

    The first method to find LCM for numbers 54 and 90 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 54 and 90 is 18, so

    LCM = (54 × 90) ÷ 18

    LCM = 4860 ÷ 18

    LCM = 270

    Finding LCM for 54 and 90 by Listing Multiples

    The second method to find LCM for numbers 54 and 90 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 54: 54, 108, 162, 216, 270, 324, 378

    Multiples of 90: 90, 180, 270, 360, 450

    So the LCM for 54 and 90 is 270

    Finding LCM for 54 and 90 by Prime Factorization

    Another method to find LCM for numbers 54 and 90 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 90: 2, 3, 3, 5 (exponent form: 21, 32, 51)

    21 × 33 × 51 = 270
