    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 9 and 28?

    Answer

    LCM of 9 and 28 is
    252

    (Two hundred fifty-two)

    Finding LCM for 9 and 28 using GCF of these numbers

    The first method to find LCM for numbers 9 and 28 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 9 and 28 is 1, so

    LCM = (9 × 28) ÷ 1

    LCM = 252 ÷ 1

    LCM = 252

    Finding LCM for 9 and 28 by Listing Multiples

    The second method to find LCM for numbers 9 and 28 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, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180, 189, 198, 207, 216, 225, 234, 243, 252, 261, 270

    Multiples of 28: 28, 56, 84, 112, 140, 168, 196, 224, 252, 280, 308

    So the LCM for 9 and 28 is 252

    Finding LCM for 9 and 28 by Prime Factorization

    Another method to find LCM for numbers 9 and 28 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 28: 2, 2, 7 (exponent form: 22, 71)

    32 × 22 × 71 = 252
