    How-to: What is the LCM of 128 and 194?

    The below solved example with step by step work shows how to find what is the lcm of 128 and 194 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 128 and 194?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 128
    B = 194

    What to be found:
    find the lcm of 128 and 194

    step 2 Find the prime factors of 128 and 194:
    Prime factors of 128 = 2 x 2 x 2 x 2 x 2 x 2 x 2
    Prime factors of 194 = 2 x 97

    {2} is the most repeated factor and {2 x 2 x 2 x 2 x 2 x 2 x 97} are the non-repeated factors of 128 and 194.

    step 4 Find the product of repeated and non-repeated prime factors of 128 and 194:
    = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 97
    = 12416
    lcm(128 and 194) = 12416

    Hence,
    lcm of 128 and 194 is 12416


    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 128 and 194.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 128 and 194

    What to be found:
    lcm (128, 194) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    128 and 194

    step 3 Choose the divisor which divides each or most of the given integers (128 and 194), 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 128 and 194 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2128194
    26497
    23297
