Least Common Multiple (LCM) of 234 and 238 with the help of Prime Factorisation
One method for determining the LCM of 234 and 238 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 234's prime factorization:
| 2 | 234 |
| 3 | 117 |
| 3 | 39 |
| 13 | 13 |
| 1 |
Prime factors of 234 are 2, 3,13.
234 = 21×32×131
And this is 238's prime factorization:
| 2 | 238 |
| 7 | 119 |
| 17 | 17 |
| 1 |
Prime factors of 238 are 2, 7,17.
238 = 21×71×171
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, 3,13, 7,17
.21×32×71×131×171 = 27846
This shows that the LCM of 234 and 238 is 27846.
