    How-to: What is the LCM of 84 and 106?

    The below solved example with step by step work shows how to find what is the lcm of 84 and 106 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 84 and 106?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 84
    B = 106

    What to be found:
    find the lcm of 84 and 106

    step 2 Find the prime factors of 84 and 106:
    Prime factors of 84 = 2 x 2 x 3 x 7
    Prime factors of 106 = 2 x 53

    step 3 Identify the repeated and non-repeated prime factors of 84 and 106:
    {2} is the most repeated factor and {2 x 3 x 7 x 53} are the non-repeated factors of 84 and 106.

    step 4 Find the product of repeated and non-repeated prime factors of 84 and 106:
    = 2 x 2 x 3 x 7 x 53
    = 4452
    lcm(84 and 106) = 4452

    Hence,
    lcm of 84 and 106 is 4452


    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 84 and 106.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 84 and 106

    What to be found:
    lcm (84, 106) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    84 and 106

    step 3 Choose the divisor which divides each or most of the given integers (84 and 106), 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 84 and 106 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    284106
    24253
    32153
    7753
    53153
    11
