Given numbers are 258,261,783,459
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 258,261,783,459 is 1144746.
Find LCM of 258,261,783,459 with Prime Factorization
| 3 | 258, 261, 783, 459 |
| 3 | 86, 87, 261, 153 |
| 3 | 86, 29, 87, 51 |
| 29 | 86, 29, 29, 17 |
| 86, 1, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 29 x 86 x 1 x 1 x 17 = 1144746
Therefore, the lowest common multiple of 258,261,783,459 is 1144746.
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.
258 x 261 x 783 x 459 = 24201075186
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.
258 : 1, 2, 3, 6, 43, 86, 129, 258
261 : 1, 3, 9, 29, 87, 261
783 : 1, 3, 9, 27, 29, 87, 261, 783
459 : 1, 3, 9, 17, 27, 51, 153, 459
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,261,783,459, is 3.
Now, the common factors can be found like this.
258:2x 3x 43
261:3x 3x 29
783:3x 3x 3x 29
459:3x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 29 = 7047
Therefore, the value for common factors is 7047.
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 = 24201075186/(3x7047)
LCM = 24201075186/21141
LCM = 1144746
Thus, we can understand that the LCM of 258,261,783,459 is 1144746.
