    What's the Least Common Multiple (LCM) of 75 and 90?

    Answer

    LCM of 75 and 90 is
    450

    (Four hundred fifty)

    Finding LCM for 75 and 90 using GCF of these numbers

    The first method to find LCM for numbers 75 and 90 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 75 and 90 is 15, so

    LCM = (75 × 90) ÷ 15

    LCM = 6,750 ÷ 15

    LCM = 450

    Finding LCM for 75 and 90 by Listing Multiples

    The second method to find LCM for numbers 75 and 90 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 75: 75, 150, 225, 300, 375, 450, 525, 600

    Multiples of 90: 90, 180, 270, 360, 450, 540, 630

    So the LCM for 75 and 90 is 450

    Finding LCM for 75 and 90 by Prime Factorization

    Another method to find LCM for numbers 75 and 90 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 75: 3, 5, 5 (exponent form: 31, 52)

    All Prime Factors of 90: 2, 3, 3, 5 (exponent form: 21, 32, 51)

    32 × 52 × 21 = 450
