Least Common Multiple (LCM) of 261 and 267 with the help of Prime Factorisation
One method for determining the LCM of 261 and 267 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:
Here is 261's prime factorization:
| 3 | 261 |
| 3 | 87 |
| 29 | 29 |
| 1 |
Prime factors of 261 are 3,29.
261 = 32×291
And this is 267's prime factorization:
| 3 | 267 |
| 89 | 89 |
| 1 |
Prime factors of 267 are 3,89.
267 = 31×891
When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered: 3,29,89
.32×291×891 = 23229
This shows that the LCM of 261 and 267 is 23229.
How to Calculate the LCM of 261 and 267 Using Common Multiples
