    what is the lcm of 24, 32 and 56?
    lcm (24   32   56) = (?)
    24 => 2 x 2 x 2 x 3
    32 => 2 x 2 x 2 x 2 x 2
    56 => 2 x 2 x 2 x 7

    = 2 x 2 x 2 x 3 x 2 x 2 x 7
    = 672
    lcm (24, 32 and 56) = 672
    672 is the lcm of 24, 32 and 56.

    where,
    24 is a positive integer,
    32 is a positive integer,
    672 is the lcm of 24, 32 and 56,
    {2, 2, 2} in {2 x 2 x 2 x 3, 2 x 2 x 2 x 2 x 2, 2 x 2 x 2 x 7} are the most repeated factors of 24, 32 and 56,
    {3, 2, 2, 7} in {2 x 2 x 2 x 3, 2 x 2 x 2 x 2 x 2, 2 x 2 x 2 x 7} are the the other remaining factors of 24, 32 and 56.

    Use in Mathematics: LCM of 24, 32 and 56
    The below are some of the mathematical applications where lcm of 24, 32 and 56 can be used:

    1. to find the least number which is exactly divisible by 24, 32 and 56.
    2. to find the common denominators for the fractions having 24, 32 and 56 as denominators in the unlike fractions addition or subtraction.
    Use in Real-world Problems: 24, 32 and 56 lcm
    In the context of lcm real world problems, the lcm of 24, 32 and 56 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 32 seconds and C tolls at 56 seconds repeatedly. The answer is that all bells A, B and C toll together at 672 seconds for the first time, at 1344 seconds for the second time, at 2016 seconds for the third time and so on.

    Important Notes: 24, 32 and 56 lcm
    The below are the important notes to be remembered while solving the lcm of 24, 32 and 56:
    1. The repeated and non-repeated prime factors of 24, 32 and 56 should be multiplied to find the least common multiple of 24, 32 and 56, when solving lcm by using prime factors method.
    2. The results of lcm of 24, 32 and 56 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, 32 and 56?

    The below solved example with step by step work shows how to find what is the lcm of 24, 32 and 56 by using either prime factors method and special division method.

    Solved example using prime factors method:
    What is the LCM of 24, 32 and 56?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 24
    B = 32
    C = 56

    What to be found:
    find the lcm of 24, 32 and 56

    step 2 Find the prime factors of 24, 32 and 56:
    Prime factors of 24 = 2 x 2 x 2 x 3
    Prime factors of 32 = 2 x 2 x 2 x 2 x 2
    Prime factors of 56 = 2 x 2 x 2 x 7

    step 3 Identify the repeated and non-repeated prime factors of 24, 32 and 56:
    {2, 2, 2} are the most repeated factors and {3, 2, 2, 7} are the non-repeated factors of 24, 32 and 56.

    step 4 Find the product of repeated and non-repeated prime factors of 24, 32 and 56:
    = 2 x 2 x 2 x 3 x 2 x 2 x 7
    = 672
    lcm(20 and 30) = 672

    Hence,
    lcm of 24, 32 and 56 is 672


    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, 32 and 56.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 24, 32 and 56

    What to be found:
    lcm (24, 32, 56) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    24, 32 and 56

    step 3 Choose the divisor which divides each or most of the given integers (24, 32 and 56), 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, 32 and 56 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2243256
    2121628
    26814
    2347
    2327
    3317
    7117
    111

    step 4 Multiply the divisors to find the lcm of 24, 32 and 56:
    = 2 x 2 x 2 x 2 x 2 x 3 x 7
    = 672
    LCM(24, 32, 56) = 672

    The least common multiple for three numbers 24, 32 and 56 is 672
