    = 2 x 13 x 2 x 3
    = 156
    lcm (26, 52 and 78) = 156
    156 is the lcm of 26, 52 and 78.

    where,
    26 is a positive integer,
    52 is a positive integer,
    156 is the lcm of 26, 52 and 78,
    {2, 13} in {2 x 13, 2 x 2 x 13, 2 x 3 x 13} are the most repeated factors of 26, 52 and 78,
    {2, 3} in {2 x 13, 2 x 2 x 13, 2 x 3 x 13} are the the other remaining factors of 26, 52 and 78.

    Use in Mathematics: LCM of 26, 52 and 78
    The below are some of the mathematical applications where lcm of 26, 52 and 78 can be used:

    1. to find the least number which is exactly divisible by 26, 52 and 78.
    2. to find the common denominators for the fractions having 26, 52 and 78 as denominators in the unlike fractions addition or subtraction.
    Use in Real-world Problems: 26, 52 and 78 lcm
    In the context of lcm real world problems, the lcm of 26, 52 and 78 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 26 seconds, B tolls at 52 seconds and C tolls at 78 seconds repeatedly. The answer is that all bells A, B and C toll together at 156 seconds for the first time, at 312 seconds for the second time, at 468 seconds for the third time and so on.

    Important Notes: 26, 52 and 78 lcm
    The below are the important notes to be remembered while solving the lcm of 26, 52 and 78:

    How-to: What is the LCM of 26, 52 and 78?

    The below solved example with step by step work shows how to find what is the lcm of 26, 52 and 78 by using either prime factors method and special division method.

    Solved example using prime factors method:
    What is the LCM of 26, 52 and 78?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 26
    B = 52
    C = 78

    What to be found:
    find the lcm of 26, 52 and 78

    step 2 Find the prime factors of 26, 52 and 78:
    Prime factors of 26 = 2 x 13
    Prime factors of 52 = 2 x 2 x 13
    Prime factors of 78 = 2 x 3 x 13

    step 3 Identify the repeated and non-repeated prime factors of 26, 52 and 78:
    {2, 13} are the most repeated factors and {2, 3} are the non-repeated factors of 26, 52 and 78.

    step 4 Find the product of repeated and non-repeated prime factors of 26, 52 and 78:
    = 2 x 13 x 2 x 3
    = 156
    lcm(20 and 30) = 156

    Hence,
    lcm of 26, 52 and 78 is 156


    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 26, 52 and 78.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 26, 52 and 78

    What to be found:
    lcm (26, 52, 78) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    26, 52 and 78

    step 3 Choose the divisor which divides each or most of the given integers (26, 52 and 78), 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 26, 52 and 78 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2265278
    2132639
    3131339
    13131313
    111

    step 4 Multiply the divisors to find the lcm of 26, 52 and 78:
    = 2 x 2 x 3 x 13
    = 156
    LCM(26, 52, 78) = 156

    The least common multiple for three numbers 26, 52 and 78 is 156
