    What's the Least Common Multiple (LCM) of 54 and 81?

    Answer

    LCM of 54 and 81 is
    162

    (One hundred sixty-two)

    Finding LCM for 54 and 81 using GCF of these numbers

    The first method to find LCM for numbers 54 and 81 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 54 and 81 is 27, so

    LCM = (54 × 81) ÷ 27

    LCM = 4,374 ÷ 27

    LCM = 162

    Finding LCM for 54 and 81 by Listing Multiples

    The second method to find LCM for numbers 54 and 81 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

    Multiples of 81: 81, 162, 243, 324

    So the LCM for 54 and 81 is 162

    Finding LCM for 54 and 81 by Prime Factorization

    Another method to find LCM for numbers 54 and 81 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 81: 3, 3, 3, 3 (exponent form: 34)

    21 × 34 = 162
