    How-to: What is the LCM of 125 and 200?

    The below solved example with step by step work shows how to find what is the lcm of 125 and 200 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 125 and 200?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 125
    B = 200

    What to be found:
    find the lcm of 125 and 200

    step 2 Find the prime factors of 125 and 200:
    Prime factors of 125 = 5 x 5 x 5
    Prime factors of 200 = 2 x 2 x 2 x 5 x 5

    step 3 Identify the repeated and non-repeated prime factors of 125 and 200:
    {5, 5} are the most repeated factors and {5 x 2 x 2 x 2} are the non-repeated factors of 125 and 200.

    step 4 Find the product of repeated and non-repeated prime factors of 125 and 200:
    = 5 x 5 x 5 x 2 x 2 x 2
    = 1000
    lcm(125 and 200) = 1000

    Hence,
    lcm of 125 and 200 is 1000


    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 125 and 200.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 125 and 200

    What to be found:
    lcm (125, 200) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    125 and 200

    step 3 Choose the divisor which divides each or most of the given integers (125 and 200), 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 125 and 200 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2125200
    2125100
    212550
    512525
    5255
    551
    11
