Given numbers are 218,258,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,258,129 is 28122.
Find LCM of 218,258,129 with Prime Factorization
| 2 | 218, 258, 129 |
| 3 | 109, 129, 129 |
| 43 | 109, 43, 43 |
| 109, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 109 x 1 x 1 = 28122
Therefore, the lowest common multiple of 218,258,129 is 28122.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
218 x 258 x 129 = 7255476
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
218 : 1, 2, 109, 218
258 : 1, 2, 3, 6, 43, 86, 129, 258
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,258,129, is 1.
Now, the common factors can be found like this.
218:2x 109
258:2x 3x 43
129:3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 43 = 258
Therefore, the value for common factors is 258.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 7255476/(1x258)
LCM = 7255476/258
LCM = 28122
Thus, we can understand that the LCM of 218,258,129 is 28122.
