    {29} is the most repeated factor and {3 x 2 x 2} are the non-repeated factors of 87 and 116.

    step 4 Find the product of repeated and non-repeated prime factors of 87 and 116:
    = 29 x 3 x 2 x 2
    = 348
    lcm(87 and 116) = 348

    Hence,
    lcm of 87 and 116 is 348


    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 87 and 116.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 87 and 116

    What to be found:
    lcm (87, 116) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    87 and 116

    step 3 Choose the divisor which divides each or most of the given integers (87 and 116), 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 87 and 116 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    287116
    28758
    38729
    292929
    11

    step 4 Multiply the divisors to find the lcm of 87 and 116:
