The answer is that all bells A, B and C toll together at 864 seconds for the first time, at 1728 seconds for the second time, at 2592 seconds for the third time and so on.
Important Notes: 32, 48 and 54 lcm
The below are the important notes to be remembered while solving the lcm of 32, 48 and 54:
- The repeated and non-repeated prime factors of 32, 48 and 54 should be multiplied to find the least common multiple of 32, 48 and 54, when solving lcm by using prime factors method.
- The results of lcm of 32, 48 and 54 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 32, 48 and 54?
The below solved example with step by step work shows how to find what is the lcm of 32, 48 and 54 by using either prime factors method and special division method.
Solved example using prime factors method:
What is the LCM of 32, 48 and 54?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 32
B = 48
C = 54
What to be found:
find the lcm of 32, 48 and 54
step 2 Find the prime factors of 32, 48 and 54:
Prime factors of 32 = 2 x 2 x 2 x 2 x 2
Prime factors of 48 = 2 x 2 x 2 x 2 x 3
Prime factors of 54 = 2 x 3 x 3 x 3
step 3 Identify the repeated and non-repeated prime factors of 32, 48 and 54:
{2, 2, 2, 2, 3} are the most repeated factors and {2, 3, 3} are the non-repeated factors of 32, 48 and 54.
step 4 Find the product of repeated and non-repeated prime factors of 32, 48 and 54:
= 2 x 2 x 2 x 2 x 3 x 2 x 3 x 3
= 864
lcm(20 and 30) = 864
Hence,
lcm of 32, 48 and 54 is 864
This special division method is the easiest way to understand the entire calculation of what is the lcm of 32, 48 and 54.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 32, 48 and 54
What to be found:
lcm (32, 48, 54) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
32, 48 and 54
step 3 Choose the divisor which divides each or most of the given integers (32, 48 and 54), 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 32, 48 and 54 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 32 | 48 | 54 |
| 2 | 16 | 24 | 27 |
