Given numbers are 489,906,715,638,190
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,906,715,638,190 is 58179963270.
Find LCM of 489,906,715,638,190 with Prime Factorization
| 2 | 489, 906, 715, 638, 190 |
| 3 | 489, 453, 715, 319, 95 |
| 5 | 163, 151, 715, 319, 95 |
| 11 | 163, 151, 143, 319, 19 |
| 163, 151, 13, 29, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 163 x 151 x 13 x 29 x 19 = 58179963270
Therefore, the lowest common multiple of 489,906,715,638,190 is 58179963270.
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.
489 x 906 x 715 x 638 x 190 = 38398775758200
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.
489 : 1, 3, 163, 489
906 : 1, 2, 3, 6, 151, 302, 453, 906
715 : 1, 5, 11, 13, 55, 65, 143, 715
638 : 1, 2, 11, 22, 29, 58, 319, 638
190 : 1, 2, 5, 10, 19, 38, 95, 190
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,906,715,638,190, is 1.
Now, the common factors can be found like this.
489:3x 163
906:2x 3x 151
715:5x 11x 13
638:2x 11x 29
190:2x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 38398775758200/(1x660)
LCM = 38398775758200/660
LCM = 58179963270
Thus, we can understand that the LCM of 489,906,715,638,190 is 58179963270.
