The answer is that all bells A, B and C toll together at 2752 seconds for the first time, at 5504 seconds for the second time, at 8256 seconds for the third time and so on.
Important Notes: 32, 64 and 86 lcm
The below are the important notes to be remembered while solving the lcm of 32, 64 and 86:
- The repeated and non-repeated prime factors of 32, 64 and 86 should be multiplied to find the least common multiple of 32, 64 and 86, when solving lcm by using prime factors method.
- The results of lcm of 32, 64 and 86 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 32, 64 and 86?
The below solved example with step by step work shows how to find what is the lcm of 32, 64 and 86 by using either prime factors method and special division method.
Solved example using prime factors method:
What is LCM of 32, 64 and 86?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 32
B = 64
C = 86
What to be found:
Find lcm of 32, 64 and 86
step 2 Find the prime factors of 32, 64 and 86:
Prime factors of 32 = 2 x 2 x 2 x 2 x 2
Prime factors of 64 = 2 x 2 x 2 x 2 x 2 x 2
Prime factors of 86 = 2 x 43
step 3 Identify the repeated and non-repeated prime factors of 32, 64 and 86:
{2, 2, 2, 2, 2} are the most repeated factors and {2, 43} are the non-repeated factors of 32, 64 and 86.
step 4 Find the product of repeated and non-repeated prime factors of 32, 64 and 86:
= 2 x 2 x 2 x 2 x 2 x 2 x 43
= 2752
LCM(32, 64 and 86) = 2752
Hence,
The Least Common Multiple of 32, 64 and 86 is 2752
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 32, 64 and 86.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 32, 64 and 86
What to be found:
lcm (32, 64, 86) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
32, 64 and 86
step 3 Choose the divisor which divides each or most of the given integers (32, 64 and 86), 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, 64 and 86 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 32 | 64 | 86 |
| 2 | 16 | 32 | 43 |
