    How-to: What is the LCM of 105 and 150?

    The below solved example with step by step work shows how to find what is the lcm of 105 and 150 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 105 and 150?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 105
    B = 150

    What to be found:
    find the lcm of 105 and 150

    step 2 Find the prime factors of 105 and 150:
    Prime factors of 105 = 3 x 5 x 7
    Prime factors of 150 = 2 x 3 x 5 x 5

    step 3 Identify the repeated and non-repeated prime factors of 105 and 150:
    {3, 5} are the most repeated factors and {7 x 2 x 5} are the non-repeated factors of 105 and 150.

    step 4 Find the product of repeated and non-repeated prime factors of 105 and 150:
    = 3 x 5 x 7 x 2 x 5
    = 1050
    lcm(105 and 150) = 1050

    Hence,
    lcm of 105 and 150 is 1050


    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 105 and 150.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 105 and 150

    What to be found:
    lcm (105, 150) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    105 and 150

    step 3 Choose the divisor which divides each or most of the given integers (105 and 150), 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 105 and 150 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2105150
    310575
    53525
    575
    771
    11
