    what is the lcm of 24, 26 and 28?
    lcm (24   26   28) = (?)
    24 => 2 x 2 x 2 x 3
    26 => 2 x 13
    28 => 2 x 2 x 7

    = 2 x 2 x 2 x 3 x 13 x 7
    = 2184
    lcm (24, 26 and 28) = 2184
    2184 is the lcm of 24, 26 and 28.

    where,
    24 is a positive integer,
    26 is a positive integer,
    2184 is the lcm of 24, 26 and 28,
    {2, 2} in {2 x 2 x 2 x 3, 2 x 13, 2 x 2 x 7} are the most repeated factors of 24, 26 and 28,
    {2, 3, 13, 7} in {2 x 2 x 2 x 3, 2 x 13, 2 x 2 x 7} are the the other remaining factors of 24, 26 and 28.

    Use in Mathematics: LCM of 24, 26 and 28
    The below are some of the mathematical applications where lcm of 24, 26 and 28 can be used:

    1. to find the least number which is exactly divisible by 24, 26 and 28.
    2. to find the common denominators for the fractions having 24, 26 and 28 as denominators in the unlike fractions addition or subtraction.
    Use in Real-world Problems: 24, 26 and 28 lcm
    In the context of lcm real world problems, the lcm of 24, 26 and 28 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 24 seconds, B tolls at 26 seconds and C tolls at 28 seconds repeatedly. The answer is that all bells A, B and C toll together at 2184 seconds for the first time, at 4368 seconds for the second time, at 6552 seconds for the third time and so on.

    Important Notes: 24, 26 and 28 lcm
    The below are the important notes to be remembered while solving the lcm of 24, 26 and 28:
    1. The repeated and non-repeated prime factors of 24, 26 and 28 should be multiplied to find the least common multiple of 24, 26 and 28, when solving lcm by using prime factors method.
    2. The results of lcm of 24, 26 and 28 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 24, 26 and 28?

    The below solved example with step by step work shows how to find what is the lcm of 24, 26 and 28 by using either prime factors method and special division method.

    Solved example using prime factors method:
    What is the LCM of 24, 26 and 28?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 24
    B = 26
    C = 28

    What to be found:
    find the lcm of 24, 26 and 28

    step 2 Find the prime factors of 24, 26 and 28:
    Prime factors of 24 = 2 x 2 x 2 x 3
    Prime factors of 26 = 2 x 13
    Prime factors of 28 = 2 x 2 x 7

    step 3 Identify the repeated and non-repeated prime factors of 24, 26 and 28:
    {2, 2} are the most repeated factors and {2, 3, 13, 7} are the non-repeated factors of 24, 26 and 28.

    step 4 Find the product of repeated and non-repeated prime factors of 24, 26 and 28:
    = 2 x 2 x 2 x 3 x 13 x 7
    = 2184
    lcm(20 and 30) = 2184

    Hence,
    lcm of 24, 26 and 28 is 2184


    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 24, 26 and 28.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 24, 26 and 28

    What to be found:
    lcm (24, 26, 28) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    24, 26 and 28

    step 3 Choose the divisor which divides each or most of the given integers (24, 26 and 28), 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 24, 26 and 28 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2242628
    2121314
    26137
    33137
    71137
    131131
    111

    step 4 Multiply the divisors to find the lcm of 24, 26 and 28:
    = 2 x 2 x 2 x 3 x 7 x 13
    = 2184
    LCM(24, 26, 28) = 2184

    The least common multiple for three numbers 24, 26 and 28 is 2184
