    58 => 2 x 29

    = 2 x 3 x 2 x 3 x 7 x 29
    = 7308
    lcm (36, 42 and 58) = 7308
    7308 is the lcm of 36, 42 and 58.

    where,
    36 is a positive integer,
    42 is a positive integer,
    7308 is the lcm of 36, 42 and 58,
    {2, 3} in {2 x 2 x 3 x 3, 2 x 3 x 7, 2 x 29} are the most repeated factors of 36, 42 and 58,
    {2, 3, 7, 29} in {2 x 2 x 3 x 3, 2 x 3 x 7, 2 x 29} are the the other remaining factors of 36, 42 and 58.

    Use in Mathematics: LCM of 36, 42 and 58
    The below are some of the mathematical applications where lcm of 36, 42 and 58 can be used:

    1. to find the least number which is exactly divisible by 36, 42 and 58.
    2. to find the common denominators for the fractions having 36, 42 and 58 as denominators in the unlike fractions addition or subtraction.
    Use in Real-world Problems: 36, 42 and 58 lcm
    In the context of lcm real world problems, the lcm of 36, 42 and 58 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 36 seconds, B tolls at 42 seconds and C tolls at 58 seconds repeatedly. The answer is that all bells A, B and C toll together at 7308 seconds for the first time, at 14616 seconds for the second time, at 21924 seconds for the third time and so on.

    Important Notes: 36, 42 and 58 lcm
    The below are the important notes to be remembered while solving the lcm of 36, 42 and 58:
    1. The repeated and non-repeated prime factors of 36, 42 and 58 should be multiplied to find the least common multiple of 36, 42 and 58, when solving lcm by using prime factors method.
    2. The results of lcm of 36, 42 and 58 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 36, 42 and 58?

    The below solved example with step by step work shows how to find what is the lcm of 36, 42 and 58 by using either prime factors method and special division method.

    Solved example using prime factors method:
    What is the LCM of 36, 42 and 58?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 36
    B = 42
    C = 58

    What to be found:
    find the lcm of 36, 42 and 58

    step 2 Find the prime factors of 36, 42 and 58:
    Prime factors of 36 = 2 x 2 x 3 x 3
    Prime factors of 42 = 2 x 3 x 7
    Prime factors of 58 = 2 x 29

    step 3 Identify the repeated and non-repeated prime factors of 36, 42 and 58:
    {2, 3} are the most repeated factors and {2, 3, 7, 29} are the non-repeated factors of 36, 42 and 58.

    step 4 Find the product of repeated and non-repeated prime factors of 36, 42 and 58:
    = 2 x 3 x 2 x 3 x 7 x 29
    = 7308
    lcm(20 and 30) = 7308

    Hence,
    lcm of 36, 42 and 58 is 7308


    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 36, 42 and 58.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 36, 42 and 58

    What to be found:
    lcm (36, 42, 58) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    36, 42 and 58

    step 3 Choose the divisor which divides each or most of the given integers (36, 42 and 58), 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 36, 42 and 58 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2364258
    2182129
    392129
    33729
    71729
    291129
    111

    step 4 Multiply the divisors to find the lcm of 36, 42 and 58:
    = 2 x 2 x 3 x 3 x 7 x 29
    = 7308
    LCM(36, 42, 58) = 7308

    The least common multiple for three numbers 36, 42 and 58 is 7308
