    where,
    40 is a positive integer,
    54 is a positive integer,
    4320 is the lcm of 40, 54 and 96,
    {2, 2, 2, 3} in {2 x 2 x 2 x 5, 2 x 3 x 3 x 3, 2 x 2 x 2 x 2 x 2 x 3} are the most repeated factors of 40, 54 and 96,
    {5, 3, 3, 2, 2} in {2 x 2 x 2 x 5, 2 x 3 x 3 x 3, 2 x 2 x 2 x 2 x 2 x 3} are the the other remaining factors of 40, 54 and 96.

    Use in Mathematics: LCM of 40, 54 and 96
    The below are some of the mathematical applications where lcm of 40, 54 and 96 can be used:

    1. to find the least number which is exactly divisible by 40, 54 and 96.
    2. to find the common denominators for the fractions having 40, 54 and 96 as denominators in the unlike fractions addition or subtraction.
    Use in Real-world Problems: 40, 54 and 96 lcm
    In the context of lcm real world problems, the lcm of 40, 54 and 96 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 40 seconds, B tolls at 54 seconds and C tolls at 96 seconds repeatedly. The answer is that all bells A, B and C toll together at 4320 seconds for the first time, at 8640 seconds for the second time, at 12960 seconds for the third time and so on.

    Important Notes: 40, 54 and 96 lcm
    The below are the important notes to be remembered while solving the lcm of 40, 54 and 96:
    1. The repeated and non-repeated prime factors of 40, 54 and 96 should be multiplied to find the least common multiple of 40, 54 and 96, when solving lcm by using prime factors method.
    2. The results of lcm of 40, 54 and 96 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 40, 54 and 96?

    The below solved example with step by step work shows how to find what is the lcm of 40, 54 and 96 by using either prime factors method and special division method.

    Solved example using prime factors method:
    What is the LCM of 40, 54 and 96?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 40
    B = 54
    C = 96

    What to be found:
    find the lcm of 40, 54 and 96

    step 2 Find the prime factors of 40, 54 and 96:
    Prime factors of 40 = 2 x 2 x 2 x 5
    Prime factors of 54 = 2 x 3 x 3 x 3
    Prime factors of 96 = 2 x 2 x 2 x 2 x 2 x 3

    step 3 Identify the repeated and non-repeated prime factors of 40, 54 and 96:
    {2, 2, 2, 3} are the most repeated factors and {5, 3, 3, 2, 2} are the non-repeated factors of 40, 54 and 96.

    step 4 Find the product of repeated and non-repeated prime factors of 40, 54 and 96:
    = 2 x 2 x 2 x 3 x 5 x 3 x 3 x 2 x 2
    = 4320
    lcm(20 and 30) = 4320

    Hence,
    lcm of 40, 54 and 96 is 4320


    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 40, 54 and 96.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 40, 54 and 96

    What to be found:
    lcm (40, 54, 96) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    40, 54 and 96

    step 3 Choose the divisor which divides each or most of the given integers (40, 54 and 96), 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 40, 54 and 96 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2405496
    2202748
    2102724
    252712
    25276
    35273
    3591
    3531
    5511
    111

    step 4 Multiply the divisors to find the lcm of 40, 54 and 96:
    = 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3 x 5
    = 4320
    LCM(40, 54, 96) = 4320

    The least common multiple for three numbers 40, 54 and 96 is 4320
