    How-to: What is the LCM of 68 and 102?

    The below solved example with step by step work shows how to find what is the lcm of 68 and 102 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 68 and 102?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 68
    B = 102

    What to be found:
    find the lcm of 68 and 102

    step 2 Find the prime factors of 68 and 102:
    Prime factors of 68 = 2 x 2 x 17
    Prime factors of 102 = 2 x 3 x 17

    step 3 Identify the repeated and non-repeated prime factors of 68 and 102:
    {2, 17} are the most repeated factors and {2 x 3} are the non-repeated factors of 68 and 102.

    step 4 Find the product of repeated and non-repeated prime factors of 68 and 102:
    = 2 x 17 x 2 x 3
    = 204
    lcm(68 and 102) = 204

    Hence,
    lcm of 68 and 102 is 204


    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 68 and 102.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 68 and 102

    What to be found:
    lcm (68, 102) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    68 and 102

    step 3 Choose the divisor which divides each or most of the given integers (68 and 102), 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 68 and 102 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    268102
    23451
    31751
    171717
    11

    step 4 Multiply the divisors to find the lcm of 68 and 102:
    = 2 x 2 x 3 x 17
    = 204
