    and

    What's the Least Common Multiple (LCM) of 9 and 5?

    Answer

    LCM of 9 and 5 is
    45

    (Forty-five)

    Finding LCM for 9 and 5 using GCF of these numbers

    The first method to find LCM for numbers 9 and 5 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 9 and 5 is 1, so

    LCM = (9 × 5) ÷ 1

    LCM = 45 ÷ 1

    LCM = 45

    Finding LCM for 9 and 5 by Listing Multiples

    The second method to find LCM for numbers 9 and 5 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 9: 9, 18, 27, 36, 45, 54, 63

    Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55

    So the LCM for 9 and 5 is 45

    Finding LCM for 9 and 5 by Prime Factorization

    Another method to find LCM for numbers 9 and 5 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 9: 3, 3 (exponent form: 32)

    All Prime Factors of 5: 5 (exponent form: 51)

    32 × 51 = 45
