Least Common Multiple (LCM) of 158 and 165 with the help of Prime Factorisation
One method for determining the LCM of 158 and 165 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 158's prime factorization:
| 2 | 158 |
| 79 | 79 |
| 1 |
Prime factors of 158 are 2,79.
158 = 21×791
And this is 165's prime factorization:
| 3 | 165 |
| 5 | 55 |
| 11 | 11 |
| 1 |
Prime factors of 165 are 3, 5,11.
165 = 31×51×111
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: 2,79, 3, 5,11
.21×31×51×111×791 = 26070
This shows that the LCM of 158 and 165 is 26070.
