    LCM - Least Common Multiple Calculator

    LCM of 10 and 5 is equal to 10. The comprehensive work provides more insight of how to find what is the lcm of 10 and 5 by using prime factors and special division methods, and the example use case of mathematics and real world problems.

    what is the lcm of 10 and 5?
    lcm (10   5) = (?)
    10 => 2 x 5
    5 => 5

    = 5 x 2
    = 10
    lcm (10 and 5) = 10
    10 is the lcm of 10 and 5.

    where,
    10 is a positive integer,
    5 is a positive integer,
    10 is the lcm of 10 and 5,
    {5} in {2 x 5, 5} is the common factors of 10 and 5,
    {2} in {2 x 5, 5} is the uncommon factors of 10 and 5.

    Use in Mathematics: LCM of 10 and 5
    The below are some of the mathematical applications where lcm of 10 and 5 can be used:

    1. to find the least number which is exactly divisible by 10 and 5.
    2. to find the common denominator for two fractions having 10 and 5 as denominators in the unlike fractions addition or subtraction.
    Use in Real-world Problems: 10 and 5 lcm
    In the context of lcm real world problems, the lcm of 10 and 5 helps to find the exact time when two similar and recurring events 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 the bells A and B all toll together, if bell A tolls at 10 seconds and bell B tolls at 5 seconds repeatedly. The answer is that all bells A and B toll together at 10 seconds for the first time, at 20 seconds for the second time, at 30 seconds for the third time and so on.

    Important Notes: 10 and 5 lcm
    The below are the important notes to be remembered while solving the lcm of 10 and 5:

    How-to: What is the LCM of 10 and 5?

    The below solved example with step by step work shows how to find what is the lcm of 10 and 5 by using prime factors method and division method.

    Solved example using prime factors method:
    What is the LCM of 10 and 5?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 10
    B = 5

    What to be found:
    find the lcm of 10 and 5

    step 2 Find the prime factors of 10 and 5:
    Prime factors of 10 = 2 x 5
    Prime factors of 5 = 5

    step 3 Identify the repeated and non-repeated prime factors of 10 and 5:
    {5} is the most repeated factor and {2} is the non-repeated factor of 10 and 5.

    step 4 Find the product of repeated and non-repeated prime factors of 10 and 5:
    = 5 x 2
    = 10
    lcm(10 and 5) = 10

    Hence,
    lcm of 10 and 5 is 10


    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 10 and 5.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 10 and 5

    What to be found:
    lcm (10, 5) = ?

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

    step 3 Choose the divisor which divides each or most of the given integers (10 and 5), 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 10 and 5 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2105
    555
    11

    step 4 Multiply the divisors to find the lcm of 10 and 5:
    = 2 x 5
    = 10
    LCM(10, 5) = 10

    The least common multiple for two numbers 10 and 5 is 10
