    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 15 and 22?

    Answer

    LCM of 15 and 22 is
    330

    (Three hundred thirty)

    Finding LCM for 15 and 22 using GCF of these numbers

    The first method to find LCM for numbers 15 and 22 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 15 and 22 is 1, so

    LCM = (15 × 22) ÷ 1

    LCM = 330 ÷ 1

    LCM = 330

    Finding LCM for 15 and 22 by Listing Multiples

    The second method to find LCM for numbers 15 and 22 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 15: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360

    Multiples of 22: 22, 44, 66, 88, 110, 132, 154, 176, 198, 220, 242, 264, 286, 308, 330, 352, 374

    So the LCM for 15 and 22 is 330

    Finding LCM for 15 and 22 by Prime Factorization

    Another method to find LCM for numbers 15 and 22 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 15: 3, 5 (exponent form: 31, 51)

    All Prime Factors of 22: 2, 11 (exponent form: 21, 111)

    31 × 51 × 21 × 111 = 330
