    How-to: What is the LCM of 96 and 120?

    The below solved example with step by step work shows how to find what is the lcm of 96 and 120 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 96 and 120?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 96
    B = 120

    What to be found:
    find the lcm of 96 and 120

    step 2 Find the prime factors of 96 and 120:
    Prime factors of 96 = 2 x 2 x 2 x 2 x 2 x 3
    Prime factors of 120 = 2 x 2 x 2 x 3 x 5

    step 3 Identify the repeated and non-repeated prime factors of 96 and 120:
    {2, 2, 2, 3} are the most repeated factors and {2 x 2 x 5} are the non-repeated factors of 96 and 120.

    step 4 Find the product of repeated and non-repeated prime factors of 96 and 120:
    = 2 x 2 x 2 x 3 x 2 x 2 x 5
    = 480
    lcm(96 and 120) = 480

    Hence,
    lcm of 96 and 120 is 480


    Solved example using special division method:
    This special division method is the easiest way to understand the entire calculation of what is the lcm of 96 and 120.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 96 and 120

    What to be found:
    lcm (96, 120) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    96 and 120

    step 3 Choose the divisor which divides each or most of the given integers (96 and 120), divide each integers separately and write down the quotient in the next line right under the respective integers. Bring down the integer to the next line if any integer in 96 and 120 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    296120
    24860
    22430
    21215
    2615
    3315
    515
    11
