    LCM for 30 and 60

    "Least Common Multiple" Calculator

    Least Common Multiple of

    and

    What's the Least Common Multiple (LCM) of 30 and 60?

    Answer

    LCM of 30 and 60 is
    60

    (Sixty)

    Finding LCM for 30 and 60 using GCF of these numbers

    The first method to find LCM for numbers 30 and 60 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 30 and 60 is 30, so

    LCM = (30 × 60) ÷ 30

    LCM = 1800 ÷ 30

    LCM = 60

    Finding LCM for 30 and 60 by Listing Multiples

    The second method to find LCM for numbers 30 and 60 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 30: 30, 60, 90, 120

    Multiples of 60: 60, 120, 180

    So the LCM for 30 and 60 is 60

    Finding LCM for 30 and 60 by Prime Factorization

    Another method to find LCM for numbers 30 and 60 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 60: 2, 2, 3, 5 (exponent form: 22, 31, 51)

    22 × 31 × 51 = 60
