Least Common Multiple (LCM) of 121 and 125 with the help of Prime Factorisation
One method for determining the LCM of 121 and 125 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 121's prime factorization:
| 11 | 121 |
| 11 | 11 |
| 1 |
Prime factors of 121 are 11.
121 = 112
And this is 125's prime factorization:
| 5 | 125 |
| 5 | 25 |
| 5 | 5 |
| 1 |
Prime factors of 125 are 5.
125 = 53
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:11,5
.53×112 = 15125
This shows that the LCM of 121 and 125 is 15125.
How to Calculate the LCM of 121 and 125 Using Common Multiples
The first step in determining the Least Common Multiple of 121 and 125 is to generate a list of multiples for each number.
