    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 4 and 30?

    Answer

    LCM of 4 and 30 is
    60

    (Sixty)

    Finding LCM for 4 and 30 using GCF of these numbers

    The first method to find LCM for numbers 4 and 30 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 4 and 30 is 2, so

    LCM = (4 × 30) ÷ 2

    LCM = 120 ÷ 2

    LCM = 60

    Finding LCM for 4 and 30 by Listing Multiples

    The second method to find LCM for numbers 4 and 30 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68

    Multiples of 30: 30, 60, 90, 120

    So the LCM for 4 and 30 is 60

    Finding LCM for 4 and 30 by Prime Factorization

    Another method to find LCM for numbers 4 and 30 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 4: 2, 2 (exponent form: 22)

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

    22 × 31 × 51 = 60
