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 1 seconds, B tolls at 10 seconds and C tolls at 1080 seconds repeatedly. The answer is that all bells A, B and C toll together at 1080 seconds for the first time, at 2160 seconds for the second time, at 3240 seconds for the third time and so on.
Important Notes: 1, 10 and 1080 lcm
The below are the important notes to be remembered while solving the lcm of 1, 10 and 1080:
- The repeated and non-repeated prime factors of 1, 10 and 1080 should be multiplied to find the least common multiple of 1, 10 and 1080, when solving lcm by using prime factors method.
- The results of lcm of 1, 10 and 1080 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 1, 10 and 1080?
The below solved example with step by step work shows how to find what is the lcm of 1, 10 and 1080 by using either prime factors method and special division method.
Solved example using prime factors method:
What is LCM of 1, 10 and 1080?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 1
B = 10
C = 1080
What to be found:
Find lcm of 1, 10 and 1080
step 2 Find the prime factors of 1, 10 and 1080:
Prime factors of 1 = 1
Prime factors of 10 = 2 x 5
Prime factors of 1080 = 2 x 2 x 2 x 3 x 3 x 3 x 5
step 3 Identify the repeated and non-repeated prime factors of 1, 10 and 1080:
{2, 5} are the most repeated factors and {1, 2, 2, 3, 3, 3} are the non-repeated factors of 1, 10 and 1080.
step 4 Find the product of repeated and non-repeated prime factors of 1, 10 and 1080:
= 2 x 5 x 1 x 2 x 2 x 3 x 3 x 3
= 1080
LCM(1, 10 and 1080) = 1080
Hence,
The Least Common Multiple of 1, 10 and 1080 is 1080
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 1, 10 and 1080.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 1, 10 and 1080
What to be found:
lcm (1, 10, 1080) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
1, 10 and 1080
step 3 Choose the divisor which divides each or most of the given integers (1, 10 and 1080), 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 1, 10 and 1080 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 1 | 10 | 1080 |
| 2 | 1 | 5 | 540 |
