    what is the lcm of 24, 63 and 70?
    lcm (24   63   70) = (?)
    24 => 2 x 2 x 2 x 3
    63 => 3 x 3 x 7
    70 => 2 x 5 x 7

    = 2 x 3 x 7 x 2 x 2 x 3 x 5
    = 2520
    lcm (24, 63 and 70) = 2520
    2520 is the lcm of 24, 63 and 70.

    where,
    24 is a positive integer,
    63 is a positive integer,
    2520 is the lcm of 24, 63 and 70,
    {2, 3, 7} in {2 x 2 x 2 x 3, 3 x 3 x 7, 2 x 5 x 7} are the most repeated factors of 24, 63 and 70,
    {2, 2, 3, 5} in {2 x 2 x 2 x 3, 3 x 3 x 7, 2 x 5 x 7} are the the other remaining factors of 24, 63 and 70.

    Use in Mathematics: LCM of 24, 63 and 70
    The below are some of the mathematical applications where lcm of 24, 63 and 70 can be used:

    1. to find the least number which is exactly divisible by 24, 63 and 70.
    2. to find the common denominators for the fractions having 24, 63 and 70 as denominators in the unlike fractions addition or subtraction.
    Use in Real-world Problems: 24, 63 and 70 lcm
    In the context of lcm real world problems, the lcm of 24, 63 and 70 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 63 seconds and C tolls at 70 seconds repeatedly. The answer is that all bells A, B and C toll together at 2520 seconds for the first time, at 5040 seconds for the second time, at 7560 seconds for the third time and so on.

    Important Notes: 24, 63 and 70 lcm
    The below are the important notes to be remembered while solving the lcm of 24, 63 and 70:
    1. The repeated and non-repeated prime factors of 24, 63 and 70 should be multiplied to find the least common multiple of 24, 63 and 70, when solving lcm by using prime factors method.
    2. The results of lcm of 24, 63 and 70 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, 63 and 70?

    The below solved example with step by step work shows how to find what is the lcm of 24, 63 and 70 by using either prime factors method and special division method.

    Solved example using prime factors method:
    What is the LCM of 24, 63 and 70?

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    A = 24
    B = 63
    C = 70

    What to be found:
    find the lcm of 24, 63 and 70

    step 2 Find the prime factors of 24, 63 and 70:
    Prime factors of 24 = 2 x 2 x 2 x 3
    Prime factors of 63 = 3 x 3 x 7
    Prime factors of 70 = 2 x 5 x 7

    step 3 Identify the repeated and non-repeated prime factors of 24, 63 and 70:
    {2, 3, 7} are the most repeated factors and {2, 2, 3, 5} are the non-repeated factors of 24, 63 and 70.

    step 4 Find the product of repeated and non-repeated prime factors of 24, 63 and 70:
    = 2 x 3 x 7 x 2 x 2 x 3 x 5
    = 2520
    lcm(20 and 30) = 2520

    Hence,
    lcm of 24, 63 and 70 is 2520


    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, 63 and 70.

    step 1 Address the input parameters, values and observe what to be found:
    Input parameters and values:
    Integers: 24, 63 and 70

    What to be found:
    lcm (24, 63, 70) = ?

    step 2 Arrange the given integers in the horizontal form with space or comma separated format:
    24, 63 and 70

    step 3 Choose the divisor which divides each or most of the given integers (24, 63 and 70), 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, 63 and 70 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

    2246370
    2126335
    266335
    336335
    312135
    51735
    7177
    111

    step 4 Multiply the divisors to find the lcm of 24, 63 and 70:
    = 2 x 2 x 2 x 3 x 3 x 5 x 7
    = 2520
    LCM(24, 63, 70) = 2520

    The least common multiple for three numbers 24, 63 and 70 is 2520
