    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 45 and 30?

    Answer

    LCM of 45 and 30 is
    90

    (Ninety)

    Finding LCM for 45 and 30 using GCF of these numbers

    The first method to find LCM for numbers 45 and 30 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 45 and 30 is 15, so

    LCM = (45 × 30) ÷ 15

    LCM = 1350 ÷ 15

    LCM = 90

    Finding LCM for 45 and 30 by Listing Multiples

    The second method to find LCM for numbers 45 and 30 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 45: 45, 90, 135, 180

    Multiples of 30: 30, 60, 90, 120, 150

    So the LCM for 45 and 30 is 90

    Finding LCM for 45 and 30 by Prime Factorization

    Another method to find LCM for numbers 45 and 30 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 30: 2, 3, 5 (exponent form: 21, 31, 51)

    32 × 51 × 21 = 90
