The LCM of 11, 13 and 24 is 3432
where,
11 is a positive integer,
13 is a positive integer,
3432 is the LCM of 11, 13 and 24,
in {11, 13, 2 x 2 x 2 x 3} there is no repeated factors of 11, 13 and 24,
{11, 13, 2, 2, 2, 3} in {11, 13, 2 x 2 x 2 x 3} are the the other remaining factors of 11, 13 and 24.
Use in Mathematics: LCM of 11, 13 and 24
The below are some of the mathematical applications where lcm of 11, 13 and 24 can be used:
- to find the least number which is exactly divisible by 11, 13 and 24.
- to find the common denominators for the fractions having 11, 13 and 24 as denominators in the unlike fractions addition or subtraction.
In the context of lcm real world problems, the lcm of 11, 13 and 24 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 13 seconds and C tolls at 24 seconds repeatedly. The answer is that all bells A, B and C toll together at 3432 seconds for the first time, at 6864 seconds for the second time, at 10296 seconds for the third time and so on.
Important Notes: 11, 13 and 24 lcm
The below are the important notes to be remembered while solving the lcm of 11, 13 and 24:
- The repeated and non-repeated prime factors of 11, 13 and 24 should be multiplied to find the least common multiple of 11, 13 and 24, when solving lcm by using prime factors method.
- The results of lcm of 11, 13 and 24 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 LCM of 11, 13 and 24?
The below solved example with step by step work shows how to find what is the lcm of 11, 13 and 24 by using either prime factors method and special division method.
Solved example using prime factors method:
What is LCM of 11, 13 and 24?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 11
B = 13
C = 24
What to be found:
Find lcm of 11, 13 and 24
step 2 Find the prime factors of 11, 13 and 24:
Prime factors of 11 = 11
Prime factors of 13 = 13
Prime factors of 24 = 2 x 2 x 2 x 3
step 3Identify the repeated and non-repeated prime factors of 11, 13 and 24:
Since there is no common factors between 11, 13 and 24, multiplying the given numbers directly provides the LCM of
11, 13 and 24.
= 11 x 13 x 24
= 3432
LCM(11, 13 and 24) = 3432
Hence,
The Least Common Multiple of 11, 13 and 24 is 3432
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 11, 13 and 24.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 11, 13 and 24
What to be found:
lcm (11, 13, 24) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
11, 13 and 24
step 3 Choose the divisor which divides each or most of the given integers (11, 13 and 24), 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, 13 and 24 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 11 | 13 | 24 |
| 2 | 11 | 13 | 12 |
| 2 | 11 | 13 | 6 |
| 3 | 11 | 13 | 3 |
| 11 | 11 | 13 | 1 |
| 13 | 1 | 13 | 1 |
| 1 | 1 | 1 |
step 4 Multiply the divisors to find the lcm of 11, 13 and 24:
= 2 x 2 x 2 x 3 x 11 x 13
= 3432
LCM(11, 13, 24) = 3432
The LCM of three numbers 11, 13 and 24 is 3432
