    What's the Least Common Multiple (LCM) of 27 and 81?

    Answer

    LCM of 27 and 81 is
    81

    (Eighty-one)

    Finding LCM for 27 and 81 using GCF of these numbers

    The first method to find LCM for numbers 27 and 81 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 27 and 81 is 27, so

    LCM = (27 × 81) ÷ 27

    LCM = 2,187 ÷ 27

    LCM = 81

    Finding LCM for 27 and 81 by Listing Multiples

    The second method to find LCM for numbers 27 and 81 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 27: 27, 54, 81, 108, 135

    Multiples of 81: 81, 162, 243

    So the LCM for 27 and 81 is 81

    Finding LCM for 27 and 81 by Prime Factorization

    Another method to find LCM for numbers 27 and 81 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 27: 3, 3, 3 (exponent form: 33)

    All Prime Factors of 81: 3, 3, 3, 3 (exponent form: 34)

    34 = 81
