Use in Mathematics: LCM of 14, 16 and 24
The below are some of the mathematical applications where lcm of 14, 16 and 24 can be used:
- to find the least number which is exactly divisible by 14, 16 and 24.
- to find the common denominators for the fractions having 14, 16 and 24 as denominators in the unlike fractions addition or subtraction.
In the context of lcm real world problems, the lcm of 14, 16 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 14 seconds, B tolls at 16 seconds and C tolls at 24 seconds repeatedly. The answer is that all bells A, B and C toll together at 336 seconds for the first time, at 672 seconds for the second time, at 1008 seconds for the third time and so on.
Important Notes: 14, 16 and 24 lcm
The below are the important notes to be remembered while solving the lcm of 14, 16 and 24:
- The repeated and non-repeated prime factors of 14, 16 and 24 should be multiplied to find the least common multiple of 14, 16 and 24, when solving lcm by using prime factors method.
- The results of lcm of 14, 16 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 the LCM of 14, 16 and 24?
The below solved example with step by step work shows how to find what is the lcm of 14, 16 and 24 by using either prime factors method and special division method.
Solved example using prime factors method:
What is the LCM of 14, 16 and 24?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 14
B = 16
C = 24
What to be found:
find the lcm of 14, 16 and 24
step 2 Find the prime factors of 14, 16 and 24:
Prime factors of 14 = 2 x 7
Prime factors of 16 = 2 x 2 x 2 x 2
Prime factors of 24 = 2 x 2 x 2 x 3
step 3 Identify the repeated and non-repeated prime factors of 14, 16 and 24:
{2, 2, 2} are the most repeated factors and {7, 2, 3} are the non-repeated factors of 14, 16 and 24.
step 4 Find the product of repeated and non-repeated prime factors of 14, 16 and 24:
= 2 x 2 x 2 x 7 x 2 x 3
= 336
lcm(20 and 30) = 336
Hence,
lcm of 14, 16 and 24 is 336
This special division method is the easiest way to understand the entire calculation of what is the lcm of 14, 16 and 24.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 14, 16 and 24
What to be found:
lcm (14, 16, 24) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
14, 16 and 24
step 3 Choose the divisor which divides each or most of the given integers (14, 16 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 14, 16 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 | 14 | 16 | 24 |
| 2 | 7 | 8 | 12 |
| 2 | 7 | 4 | 6 |
| 2 | 7 | 2 | 3 |
| 3 | 7 | 1 | 3 |
