Given numbers are 863,369,205,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 863,369,205,489 is 259534305.
Find LCM of 863,369,205,489 with Prime Factorization
| 3 | 863, 369, 205, 489 |
| 41 | 863, 123, 205, 163 |
| 863, 3, 5, 163 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 863 x 3 x 5 x 163 = 259534305
Therefore, the lowest common multiple of 863,369,205,489 is 259534305.
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.
863 x 369 x 205 x 489 = 31922719515
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.
863 : 1, 863
369 : 1, 3, 9, 41, 123, 369
205 : 1, 5, 41, 205
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,369,205,489, is 1.
Now, the common factors can be found like this.
863:863
369:3x 3x 41
205:5x 41
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 31922719515/(1x123)
LCM = 31922719515/123
LCM = 259534305
Thus, we can understand that the LCM of 863,369,205,489 is 259534305.
