    What's the Least Common Multiple (LCM) of 30 and 215?

    Answer

    LCM of 30 and 215 is
    1,290

    (One thousand two hundred ninety)

    Finding LCM for 30 and 215 using GCF of these numbers

    The first method to find LCM for numbers 30 and 215 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 30 and 215 is 5, so

    LCM = (30 × 215) ÷ 5

    LCM = 6450 ÷ 5

    LCM = 1290

    Finding LCM for 30 and 215 by Listing Multiples

    The second method to find LCM for numbers 30 and 215 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, 900, 930, 960, 990, 1020, 1050, 1080, 1110, 1140, 1170, 1200, 1230, 1260, 1290, 1320, 1350

    Multiples of 215: 215, 430, 645, 860, 1075, 1290, 1505, 1720

    So the LCM for 30 and 215 is 1290

    Finding LCM for 30 and 215 by Prime Factorization

    Another method to find LCM for numbers 30 and 215 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 215: 5, 43 (exponent form: 51, 431)

    21 × 31 × 51 × 431 = 1290
