In the context of lcm real world problems, the lcm of 26, 30 and 44 helps to find the exact time when three similar and recurring with different time schedule happens together at the same time. 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 26 seconds, B tolls at 30 seconds and C tolls at 44 seconds repeatedly. The answer is that all bells A, B and C toll together at 8580 seconds for the first time, at 17160 seconds for the second time, at 25740 seconds for the third time and so on.
Important Notes: 26, 30 and 44 lcm
The below are the important notes to be remembered while solving the lcm of 26, 30 and 44:
- The repeated and non-repeated prime factors of 26, 30 and 44 should be multiplied to find the least common multiple of 26, 30 and 44, when solving lcm by using prime factors method.
- The results of lcm of 26, 30 and 44 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 26, 30 and 44?
The below solved example with step by step work shows how to find what is the lcm of 26, 30 and 44 by using either prime factors method and special division method.
Solved example using prime factors method:
What is the LCM of 26, 30 and 44?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 26
B = 30
C = 44
What to be found:
find the lcm of 26, 30 and 44
step 2 Find the prime factors of 26, 30 and 44:
Prime factors of 26 = 2 x 13
Prime factors of 30 = 2 x 3 x 5
Prime factors of 44 = 2 x 2 x 11
step 3 Identify the repeated and non-repeated prime factors of 26, 30 and 44:
{2} is the most repeated factor and {13, 3, 5, 2, 11} are the non-repeated factors of 26, 30 and 44.
step 4 Find the product of repeated and non-repeated prime factors of 26, 30 and 44:
= 2 x 13 x 3 x 5 x 2 x 11
= 8580
lcm(20 and 30) = 8580
Hence,
lcm of 26, 30 and 44 is 8580
This special division method is the easiest way to understand the entire calculation of what is the lcm of 26, 30 and 44.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 26, 30 and 44
What to be found:
lcm (26, 30, 44) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
26, 30 and 44
step 3 Choose the divisor which divides each or most of the given integers (26, 30 and 44), 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 26, 30 and 44 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 26 | 30 | 44 |
| 2 | 13 | 15 | 22 |
| 3 | 13 | 15 | 11 |
| 5 | 13 | 5 | 11 |
