    LCM for 30 and 405

    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 30 and 405?

    Answer

    LCM of 30 and 405 is
    810

    (Eight hundred ten)

    Finding LCM for 30 and 405 using GCF of these numbers

    The first method to find LCM for numbers 30 and 405 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 30 and 405 is 15, so

    LCM = (30 × 405) ÷ 15

    LCM = 12150 ÷ 15

    LCM = 810

    Finding LCM for 30 and 405 by Listing Multiples

    The second method to find LCM for numbers 30 and 405 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 30: 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, 450, 480, 510, 540, 570, 600, 630, 660, 690, 720, 750, 780, 810, 840, 870

    Multiples of 405: 405, 810, 1215, 1620

    So the LCM for 30 and 405 is 810

    Finding LCM for 30 and 405 by Prime Factorization

    Another method to find LCM for numbers 30 and 405 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 30: 2, 3, 5 (exponent form: 21, 31, 51)

    All Prime Factors of 405: 3, 3, 3, 3, 5 (exponent form: 34, 51)

    21 × 34 × 51 = 810
