The answer is that all bells A, B and C toll together at 22950 seconds for the first time, at 45900 seconds for the second time, at 68850 seconds for the third time and so on.
Important Notes: 25, 27 and 34 lcm
The below are the important notes to be remembered while solving the lcm of 25, 27 and 34:
- The repeated and non-repeated prime factors of 25, 27 and 34 should be multiplied to find the least common multiple of 25, 27 and 34, when solving lcm by using prime factors method.
- The results of lcm of 25, 27 and 34 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 25, 27 and 34?
The below solved example with step by step work shows how to find what is the lcm of 25, 27 and 34 by using either prime factors method and special division method.
Solved example using prime factors method:
What is LCM of 25, 27 and 34?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 25
B = 27
C = 34
What to be found:
Find lcm of 25, 27 and 34
step 2 Find the prime factors of 25, 27 and 34:
Prime factors of 25 = 5 x 5
Prime factors of 27 = 3 x 3 x 3
Prime factors of 34 = 2 x 17
step 3Identify the repeated and non-repeated prime factors of 25, 27 and 34:
Since there is no common factors between 25, 27 and 34, multiplying the given numbers directly provides the LCM of
25, 27 and 34.
= 25 x 27 x 34
= 22950
LCM(25, 27 and 34) = 22950
Hence,
The Least Common Multiple of 25, 27 and 34 is 22950
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 25, 27 and 34.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 25, 27 and 34
What to be found:
lcm (25, 27, 34) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
25, 27 and 34
step 3 Choose the divisor which divides each or most of the given integers (25, 27 and 34), 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 25, 27 and 34 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 25 | 27 | 34 |
| 3 | 25 | 27 | 17 |
| 3 | 25 | 9 | 17 |
| 3 | 25 | 3 | 17 |
| 5 | 25 | 1 | 17 |
