The answer is that all bells A, B and C toll together at 1200 seconds for the first time, at 2400 seconds for the second time, at 3600 seconds for the third time and so on.
Important Notes: 48, 50 and 60 lcm
The below are the important notes to be remembered while solving the lcm of 48, 50 and 60:
- The repeated and non-repeated prime factors of 48, 50 and 60 should be multiplied to find the least common multiple of 48, 50 and 60, when solving lcm by using prime factors method.
- The results of lcm of 48, 50 and 60 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 48, 50 and 60?
The below solved example with step by step work shows how to find what is the lcm of 48, 50 and 60 by using either prime factors method and special division method.
Solved example using prime factors method:
What is LCM of 48, 50 and 60?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 48
B = 50
C = 60
What to be found:
Find lcm of 48, 50 and 60
step 2 Find the prime factors of 48, 50 and 60:
Prime factors of 48 = 2 x 2 x 2 x 2 x 3
Prime factors of 50 = 2 x 5 x 5
Prime factors of 60 = 2 x 2 x 3 x 5
step 3 Identify the repeated and non-repeated prime factors of 48, 50 and 60:
{2, 2, 3, 5} are the most repeated factors and {2, 2, 5} are the non-repeated factors of 48, 50 and 60.
step 4 Find the product of repeated and non-repeated prime factors of 48, 50 and 60:
= 2 x 2 x 3 x 5 x 2 x 2 x 5
= 1200
LCM(48, 50 and 60) = 1200
Hence,
The Least Common Multiple of 48, 50 and 60 is 1200
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 48, 50 and 60.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 48, 50 and 60
What to be found:
lcm (48, 50, 60) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
48, 50 and 60
step 3 Choose the divisor which divides each or most of the given integers (48, 50 and 60), 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 48, 50 and 60 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 48 | 50 | 60 |
| 2 | 24 | 25 | 30 |
| 2 | 12 | 25 | 15 |
