    what is the lcm of 11, 33 and 75?
    lcm (11   33   75) = (?)
    11 => 11
    33 => 3 x 11
    75 => 3 x 5 x 5

    = 3 x 11 x 5 x 5
    = 825
    lcm (11, 33 and 75) = 825
    825 is the lcm of 11, 33 and 75.

    where,
    11 is a positive integer,
    33 is a positive integer,
    825 is the lcm of 11, 33 and 75,
    {3, 11} in {11, 3 x 11, 3 x 5 x 5} are the most repeated factors of 11, 33 and 75,
    {5, 5} in {11, 3 x 11, 3 x 5 x 5} are the the other remaining factors of 11, 33 and 75.

    Use in Mathematics: LCM of 11, 33 and 75
    The below are some of the mathematical applications where lcm of 11, 33 and 75 can be used:

    1. to find the least number which is exactly divisible by 11, 33 and 75.
    2. to find the common denominators for the fractions having 11, 33 and 75 as denominators in the unlike fractions addition or subtraction.
    Use in Real-world Problems: 11, 33 and 75 lcm
    In the context of lcm real world problems, the lcm of 11, 33 and 75 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 11 seconds, B tolls at 33 seconds and C tolls at 75 seconds repeatedly. The answer is that all bells A, B and C toll together at 825 seconds for the first time, at 1650 seconds for the second time, at 2475 seconds for the third time and so on.

    Important Notes: 11, 33 and 75 lcm
    The below are the important notes to be remembered while solving the lcm of 11, 33 and 75:
    1. The repeated and non-repeated prime factors of 11, 33 and 75 should be multiplied to find the least common multiple of 11, 33 and 75, when solving lcm by using prime factors method.
    2. The results of lcm of 11, 33 and 75 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 11, 33 and 75?

    The below solved example with step by step work shows how to find what is the lcm of 11, 33 and 75 by using either prime factors method and special division method.

    Solved example using prime factors method:
    What is the LCM of 11, 33 and 75?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 11
    B = 33
    C = 75

    What to be found:
    find the lcm of 11, 33 and 75

    step 2 Find the prime factors of 11, 33 and 75:
    Prime factors of 11 = 11
    Prime factors of 33 = 3 x 11
    Prime factors of 75 = 3 x 5 x 5

    step 3 Identify the repeated and non-repeated prime factors of 11, 33 and 75:
    {3, 11} are the most repeated factors and {5, 5} are the non-repeated factors of 11, 33 and 75.

    step 4 Find the product of repeated and non-repeated prime factors of 11, 33 and 75:
    = 3 x 11 x 5 x 5
    = 825
    lcm(20 and 30) = 825

    Hence,
    lcm of 11, 33 and 75 is 825


    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 11, 33 and 75.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 11, 33 and 75

    What to be found:
    lcm (11, 33, 75) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    11, 33 and 75

    step 3 Choose the divisor which divides each or most of the given integers (11, 33 and 75), 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 11, 33 and 75 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    3113375
    5111125
    511115
    1111111
    111

    step 4 Multiply the divisors to find the lcm of 11, 33 and 75:
    = 3 x 5 x 5 x 11
    = 825
    LCM(11, 33, 75) = 825

    The least common multiple for three numbers 11, 33 and 75 is 825
