    LCM of 22 and 55 is equal to 110. The comprehensive work provides more insight of how to find what is the lcm of 22 and 55 by using prime factors and special division methods, and the example use case of mathematics and real world problems.

    what is the lcm of 22 and 55?
    lcm (22   55) = (?)
    22 => 2 x 11
    55 => 5 x 11

    = 11 x 2 x 5
    = 110
    lcm (22 and 55) = 110
    110 is the lcm of 22 and 55.

    where,
    22 is a positive integer,
    55 is a positive integer,
    110 is the lcm of 22 and 55,
    {11} in {2 x 11, 5 x 11} is the common factors of 22 and 55,
    {2 x 5} in {2 x 11, 5 x 11} are the uncommon factors of 22 and 55.

    Use in Mathematics: LCM of 22 and 55

    How-to: What is the LCM of 22 and 55?

    The below solved example with step by step work shows how to find what is the lcm of 22 and 55 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 22 and 55?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 22
    B = 55

    What to be found:
    find the lcm of 22 and 55

    step 2 Find the prime factors of 22 and 55:
    Prime factors of 22 = 2 x 11
    Prime factors of 55 = 5 x 11

    step 3 Identify the repeated and non-repeated prime factors of 22 and 55:
    {11} is the most repeated factor and {2 x 5} are the non-repeated factors of 22 and 55.

    step 4 Find the product of repeated and non-repeated prime factors of 22 and 55:
    = 11 x 2 x 5
    = 110
    lcm(22 and 55) = 110

    Hence,
    lcm of 22 and 55 is 110


    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 22 and 55.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 22 and 55

    What to be found:
    lcm (22, 55) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    22 and 55

    step 3 Choose the divisor which divides each or most of the given integers (22 and 55), 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 22 and 55 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    22255
    51155
    111111
    11

    step 4 Multiply the divisors to find the lcm of 22 and 55:
    = 2 x 5 x 11
    = 110
    LCM(22, 55) = 110

    The least common multiple for two numbers 22 and 55 is 110
