Least Common Multiple (LCM) of 143 and 148 with the help of Prime Factorisation
One method for determining the LCM of 143 and 148 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 143's prime factorization:
| 11 | 143 |
| 13 | 13 |
| 1 |
Prime factors of 143 are 11,13.
143 = 111×131
And this is 148's prime factorization:
| 2 | 148 |
| 2 | 74 |
| 37 | 37 |
| 1 |
Prime factors of 148 are 2,37.
148 = 22×371
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: 11,13, 2,37
.22×111×131×371 = 21164
This shows that the LCM of 143 and 148 is 21164.
