    LCM of 5, 25 and 65 is equal to 325. The comprehensive work provides more insight of how to find what is the lcm of 5, 25 and 65 by using prime factors and special division methods, and the example use case of mathematics and real world problems.

    what is the lcm of 5, 25 and 65?
    lcm (5   25   65) = (?)
    5 => 5
    25 => 5 x 5
    65 => 5 x 13

    = 5 x 5 x 13
    = 325
    lcm (5, 25 and 65) = 325
    325 is the lcm of 5, 25 and 65.

    where,
    5 is a positive integer,
    25 is a positive integer,
    325 is the lcm of 5, 25 and 65,
    {5} in {5, 5 x 5, 5 x 13} is the most repeated factors of 5, 25 and 65,
    {5, 13} in {5, 5 x 5, 5 x 13} are the the other remaining factors of 5, 25 and 65.

    Use in Mathematics: LCM of 5, 25 and 65
    The below are some of the mathematical applications where lcm of 5, 25 and 65 can be used:

    1. to find the least number which is exactly divisible by 5, 25 and 65.
    2. to find the common denominators for the fractions having 5, 25 and 65 as denominators in the unlike fractions addition or subtraction.
    Use in Real-world Problems: 5, 25 and 65 lcm
    In the context of lcm real world problems, the lcm of 5, 25 and 65 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 5 seconds, B tolls at 25 seconds and C tolls at 65 seconds repeatedly. The answer is that all bells A, B and C toll together at 325 seconds for the first time, at 650 seconds for the second time, at 975 seconds for the third time and so on.

    Important Notes: 5, 25 and 65 lcm
    The below are the important notes to be remembered while solving the lcm of 5, 25 and 65:
    1. The repeated and non-repeated prime factors of 5, 25 and 65 should be multiplied to find the least common multiple of 5, 25 and 65, when solving lcm by using prime factors method.
    2. The results of lcm of 5, 25 and 65 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 5, 25 and 65?

    The below solved example with step by step work shows how to find what is the lcm of 5, 25 and 65 by using either prime factors method and special division method.

    Solved example using prime factors method:
    What is the LCM of 5, 25 and 65?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 5
    B = 25
    C = 65

    What to be found:
    find the lcm of 5, 25 and 65

    step 2 Find the prime factors of 5, 25 and 65:
    Prime factors of 5 = 5
    Prime factors of 25 = 5 x 5
    Prime factors of 65 = 5 x 13

    step 3 Identify the repeated and non-repeated prime factors of 5, 25 and 65:
    {5} is the most repeated factor and {5, 13} are the non-repeated factors of 5, 25 and 65.

    step 4 Find the product of repeated and non-repeated prime factors of 5, 25 and 65:
    = 5 x 5 x 13
    = 325
    lcm(20 and 30) = 325

    Hence,
    lcm of 5, 25 and 65 is 325


    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 5, 25 and 65.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 5, 25 and 65

    What to be found:
    lcm (5, 25, 65) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    5, 25 and 65

    step 3 Choose the divisor which divides each or most of the given integers (5, 25 and 65), 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 5, 25 and 65 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    552565
    51513
    131113
    111

    step 4 Multiply the divisors to find the lcm of 5, 25 and 65:
    = 5 x 5 x 13
    = 325
    LCM(5, 25, 65) = 325

    The least common multiple for three numbers 5, 25 and 65 is 325
