    What's the Least Common Multiple (LCM) of 45 and 180?

    Answer

    LCM of 45 and 180 is
    180

    (One hundred eighty)

    Finding LCM for 45 and 180 using GCF of these numbers

    The first method to find LCM for numbers 45 and 180 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 45 and 180 is 45, so

    LCM = (45 × 180) ÷ 45

    LCM = 8,100 ÷ 45

    LCM = 180

    Finding LCM for 45 and 180 by Listing Multiples

    The second method to find LCM for numbers 45 and 180 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

    Multiples of 180: 180, 360, 540

    So the LCM for 45 and 180 is 180

    Finding LCM for 45 and 180 by Prime Factorization

    Another method to find LCM for numbers 45 and 180 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 180: 2, 2, 3, 3, 5 (exponent form: 22, 32, 51)

    32 × 51 × 22 = 180
