51 => 3 x 17

= 3 x 2 x 2 x 2 x 3 x 5 x 17
= 6120
lcm (24, 45 and 51) = 6120
6120 is the lcm of 24, 45 and 51.

where,
24 is a positive integer,
45 is a positive integer,
6120 is the lcm of 24, 45 and 51,
{3} in {2 x 2 x 2 x 3, 3 x 3 x 5, 3 x 17} is the most repeated factors of 24, 45 and 51,
{2, 2, 2, 3, 5, 17} in {2 x 2 x 2 x 3, 3 x 3 x 5, 3 x 17} are the the other remaining factors of 24, 45 and 51.

Use in Mathematics: LCM of 24, 45 and 51
The below are some of the mathematical applications where lcm of 24, 45 and 51 can be used:

1. to find the least number which is exactly divisible by 24, 45 and 51.
2. to find the common denominators for the fractions having 24, 45 and 51 as denominators in the unlike fractions addition or subtraction.
Use in Real-world Problems: 24, 45 and 51 lcm
In the context of lcm real world problems, the lcm of 24, 45 and 51 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 45 seconds and C tolls at 51 seconds repeatedly. The answer is that all bells A, B and C toll together at 6120 seconds for the first time, at 12240 seconds for the second time, at 18360 seconds for the third time and so on.

Important Notes: 24, 45 and 51 lcm
The below are the important notes to be remembered while solving the lcm of 24, 45 and 51:
1. The repeated and non-repeated prime factors of 24, 45 and 51 should be multiplied to find the least common multiple of 24, 45 and 51, when solving lcm by using prime factors method.
2. The results of lcm of 24, 45 and 51 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, 45 and 51?

The below solved example with step by step work shows how to find what is the lcm of 24, 45 and 51 by using either prime factors method and special division method.

Solved example using prime factors method:
What is the LCM of 24, 45 and 51?

step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 24
B = 45
C = 51

What to be found:
find the lcm of 24, 45 and 51

step 2 Find the prime factors of 24, 45 and 51:
Prime factors of 24 = 2 x 2 x 2 x 3
Prime factors of 45 = 3 x 3 x 5
Prime factors of 51 = 3 x 17

step 3 Identify the repeated and non-repeated prime factors of 24, 45 and 51:
{3} is the most repeated factor and {2, 2, 2, 3, 5, 17} are the non-repeated factors of 24, 45 and 51.

step 4 Find the product of repeated and non-repeated prime factors of 24, 45 and 51:
= 3 x 2 x 2 x 2 x 3 x 5 x 17
= 6120
lcm(20 and 30) = 6120

Hence,
lcm of 24, 45 and 51 is 6120

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, 45 and 51.

step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 24, 45 and 51

What to be found:
lcm (24, 45, 51) = ?

step 2 Arrange the given integers in the horizontal form with space or comma separated format:
24, 45 and 51

step 3 Choose the divisor which divides each or most of the given integers (24, 45 and 51), 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, 45 and 51 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:

 2 24 45 51 2 12 45 51 2 6 45 51 3 3 45 51 3 1 15 17 5 1 5 17 17 1 1 17 1 1 1
