Least Common Multiple (LCM) of 275 and 281 with the help of Prime Factorisation
One method for determining the LCM of 275 and 281 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 275's prime factorization:
| 5 | 275 |
| 5 | 55 |
| 11 | 11 |
| 1 |
Prime factors of 275 are 5,11.
275 = 52×111
And this is 281's prime factorization:
| 281 | 281 |
| 1 |
Prime factors of 281 are 281.
281 = 2811
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: 5,11,281
.52×111×2811 = 77275
This shows that the LCM of 275 and 281 is 77275.
How to Calculate the LCM of 275 and 281 Using Common Multiples
