Least Common Multiple (LCM) of 135 and 143 with the help of Prime Factorisation
One method for determining the LCM of 135 and 143 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 135's prime factorization:
| 3 | 135 |
| 3 | 45 |
| 3 | 15 |
| 5 | 5 |
| 1 |
Prime factors of 135 are 3,5.
135 = 33×51
And this is 143's prime factorization:
| 11 | 143 |
| 13 | 13 |
| 1 |
Prime factors of 143 are 11,13.
143 = 111×131
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: 3,5, 11,13
.33×51×111×131 = 19305
This shows that the LCM of 135 and 143 is 19305.
How to Calculate the LCM of 135 and 143 Using Common Multiples
