    How-to: What is the LCM of 90 and 93?

    The below solved example with step by step work shows how to find what is the lcm of 90 and 93 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 90 and 93?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 90
    B = 93

    What to be found:
    find the lcm of 90 and 93

    step 2 Find the prime factors of 90 and 93:
    Prime factors of 90 = 2 x 3 x 3 x 5
    Prime factors of 93 = 3 x 31

    step 3 Identify the repeated and non-repeated prime factors of 90 and 93:
    {3} is the most repeated factor and {2 x 3 x 5 x 31} are the non-repeated factors of 90 and 93.

    step 4 Find the product of repeated and non-repeated prime factors of 90 and 93:
    = 3 x 2 x 3 x 5 x 31
    = 2790
    lcm(90 and 93) = 2790

    Hence,
    lcm of 90 and 93 is 2790


    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 90 and 93.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 90 and 93

    What to be found:
    lcm (90, 93) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    90 and 93

    step 3 Choose the divisor which divides each or most of the given integers (90 and 93), 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 90 and 93 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    29093
    34593
    31531
    5531
    31131
    11

    step 4 Multiply the divisors to find the lcm of 90 and 93:
    = 2 x 3 x 3 x 5 x 31
    = 2790
    LCM(90, 93) = 2790

    The least common multiple for two numbers 90 and 93 is 2790
