    How-to: What is the LCM of 6 and 63?

    The below solved example with step by step work shows how to find what is the lcm of 6 and 63 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 6 and 63?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 6
    B = 63

    What to be found:
    find the lcm of 6 and 63

    step 2 Find the prime factors of 6 and 63:
    Prime factors of 6 = 2 x 3
    Prime factors of 63 = 3 x 3 x 7

    {3} is the most repeated factor and {2 x 3 x 7} are the non-repeated factors of 6 and 63.

    step 4 Find the product of repeated and non-repeated prime factors of 6 and 63:
    = 3 x 2 x 3 x 7
    = 126
    lcm(6 and 63) = 126

    Hence,
    lcm of 6 and 63 is 126


    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 6 and 63.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 6 and 63

    What to be found:
    lcm (6, 63) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    6 and 63

    step 3 Choose the divisor which divides each or most of the given integers (6 and 63), 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 6 and 63 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2663
    3363
    3121
    717
    11

    step 4 Multiply the divisors to find the lcm of 6 and 63:
    = 2 x 3 x 3 x 7
    = 126
    LCM(6, 63) = 126

    The least common multiple for two numbers 6 and 63 is 126
