    How-to: What is the LCM of 33 and 121?

    The below solved example with step by step work shows how to find what is the lcm of 33 and 121 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 33 and 121?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 33
    B = 121

    What to be found:
    find the lcm of 33 and 121

    step 2 Find the prime factors of 33 and 121:
    Prime factors of 33 = 3 x 11
    Prime factors of 121 = 11 x 11

    step 3 Identify the repeated and non-repeated prime factors of 33 and 121:
    {11} is the most repeated factor and {3 x 11} are the non-repeated factors of 33 and 121.

    step 4 Find the product of repeated and non-repeated prime factors of 33 and 121:
    = 11 x 3 x 11
    = 363
    lcm(33 and 121) = 363

    Hence,
    lcm of 33 and 121 is 363


    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 33 and 121.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 33 and 121

    What to be found:
    lcm (33, 121) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    33 and 121

    step 3 Choose the divisor which divides each or most of the given integers (33 and 121), 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 33 and 121 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    333121
    1111121
    11111
    11

    step 4 Multiply the divisors to find the lcm of 33 and 121:
    = 3 x 11 x 11
    = 363
    LCM(33, 121) = 363

    The least common multiple for two numbers 33 and 121 is 363
