    what is the lcm of 27, 30 and 36?
    lcm (27   30   36) = (?)
    27 => 3 x 3 x 3
    30 => 2 x 3 x 5
    36 => 2 x 2 x 3 x 3

    = 2 x 3 x 3 x 3 x 5 x 2
    = 540
    lcm (27, 30 and 36) = 540
    540 is the lcm of 27, 30 and 36.

    where,
    27 is a positive integer,
    30 is a positive integer,
    540 is the lcm of 27, 30 and 36,
    {2, 3, 3} in {3 x 3 x 3, 2 x 3 x 5, 2 x 2 x 3 x 3} are the most repeated factors of 27, 30 and 36,
    {3, 5, 2} in {3 x 3 x 3, 2 x 3 x 5, 2 x 2 x 3 x 3} are the the other remaining factors of 27, 30 and 36.

    Use in Mathematics: LCM of 27, 30 and 36
    The below are some of the mathematical applications where lcm of 27, 30 and 36 can be used:

    1. to find the least number which is exactly divisible by 27, 30 and 36.
    2. to find the common denominators for the fractions having 27, 30 and 36 as denominators in the unlike fractions addition or subtraction.
    Use in Real-world Problems: 27, 30 and 36 lcm
    In the context of lcm real world problems, the lcm of 27, 30 and 36 helps to find the exact time when three similar and recurring with different time schedule happens together at the same time. For example, the real world problems involve lcm in situations to find at what time all the bells A, B and C toll together, if bell A tolls at 27 seconds, B tolls at 30 seconds and C tolls at 36 seconds repeatedly. The answer is that all bells A, B and C toll together at 540 seconds for the first time, at 1080 seconds for the second time, at 1620 seconds for the third time and so on.

    Important Notes: 27, 30 and 36 lcm
    The below are the important notes to be remembered while solving the lcm of 27, 30 and 36:
    1. The repeated and non-repeated prime factors of 27, 30 and 36 should be multiplied to find the least common multiple of 27, 30 and 36, when solving lcm by using prime factors method.
    2. The results of lcm of 27, 30 and 36 is identical even if we change the order of given numbers in the lcm calculation, it means the order of given numbers in the lcm calculation doesn't affect the results.

    How-to: What is the LCM of 27, 30 and 36?

    The below solved example with step by step work shows how to find what is the lcm of 27, 30 and 36 by using either prime factors method and special division method.

    Solved example using prime factors method:
    What is the LCM of 27, 30 and 36?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 27
    B = 30
    C = 36

    What to be found:
    find the lcm of 27, 30 and 36

    step 2 Find the prime factors of 27, 30 and 36:
    Prime factors of 27 = 3 x 3 x 3
    Prime factors of 30 = 2 x 3 x 5
    Prime factors of 36 = 2 x 2 x 3 x 3

    step 3 Identify the repeated and non-repeated prime factors of 27, 30 and 36:
    {2, 3, 3} are the most repeated factors and {3, 5, 2} are the non-repeated factors of 27, 30 and 36.

    step 4 Find the product of repeated and non-repeated prime factors of 27, 30 and 36:
    = 2 x 3 x 3 x 3 x 5 x 2
    = 540
    lcm(20 and 30) = 540

    Hence,
    lcm of 27, 30 and 36 is 540


    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 27, 30 and 36.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 27, 30 and 36

    What to be found:
    lcm (27, 30, 36) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    27, 30 and 36

    step 3 Choose the divisor which divides each or most of the given integers (27, 30 and 36), 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 27, 30 and 36 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2273036
    2271518
    327159
    3953
    3351
    5151
    111

    step 4 Multiply the divisors to find the lcm of 27, 30 and 36:
    = 2 x 2 x 3 x 3 x 3 x 5
    = 540
    LCM(27, 30, 36) = 540

    The least common multiple for three numbers 27, 30 and 36 is 540
