    What's the Least Common Multiple (LCM) of 45 and 54?

    Answer

    LCM of 45 and 54 is
    270

    (Two hundred seventy)

    Finding LCM for 45 and 54 using GCF of these numbers

    The first method to find LCM for numbers 45 and 54 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 45 and 54 is 9, so

    LCM = (45 × 54) ÷ 9

    LCM = 2430 ÷ 9

    LCM = 270

    Finding LCM for 45 and 54 by Listing Multiples

    The second method to find LCM for numbers 45 and 54 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 45: 45, 90, 135, 180, 225, 270, 315, 360

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

    So the LCM for 45 and 54 is 270

    Finding LCM for 45 and 54 by Prime Factorization

    Another method to find LCM for numbers 45 and 54 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 45: 3, 3, 5 (exponent form: 32, 51)

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

    33 × 51 × 21 = 270
