    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 220 and 420?

    Answer

    LCM of 220 and 420 is
    4,620

    (Four thousand six hundred twenty)

    Finding LCM for 220 and 420 using GCF of these numbers

    The first method to find LCM for numbers 220 and 420 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 220 and 420 is 20, so

    LCM = (220 × 420) ÷ 20

    LCM = 92400 ÷ 20

    LCM = 4620

    Finding LCM for 220 and 420 by Listing Multiples

    The second method to find LCM for numbers 220 and 420 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 220: 220, 440, 660, 880, 1100, 1320, 1540, 1760, 1980, 2200, 2420, 2640, 2860, 3080, 3300, 3520, 3740, 3960, 4180, 4400, 4620, 4840, 5060

    Multiples of 420: 420, 840, 1260, 1680, 2100, 2520, 2940, 3360, 3780, 4200, 4620, 5040, 5460

    So the LCM for 220 and 420 is 4620

    Finding LCM for 220 and 420 by Prime Factorization

    Another method to find LCM for numbers 220 and 420 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 220: 2, 2, 5, 11 (exponent form: 22, 51, 111)

    All Prime Factors of 420: 2, 2, 3, 5, 7 (exponent form: 22, 31, 51, 71)

    22 × 51 × 111 × 31 × 71 = 4620
