Least Common Multiple (LCM) of 291 and 297 with the help of Prime Factorisation
One method for determining the LCM of 291 and 297 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 291's prime factorization:
| 3 | 291 |
| 97 | 97 |
| 1 |
Prime factors of 291 are 3,97.
291 = 31×971
And this is 297's prime factorization:
| 3 | 297 |
| 3 | 99 |
| 3 | 33 |
| 11 | 11 |
| 1 |
Prime factors of 297 are 3,11.
297 = 33×111
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: 3,97,11
.33×111×971 = 28809
This shows that the LCM of 291 and 297 is 28809.
How to Calculate the LCM of 291 and 297 Using Common Multiples
