Given numbers are 391,816,932,895,487
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,816,932,895,487 is 1906013236560.
Find LCM of 391,816,932,895,487 with Prime Factorization
| 2 | 391, 816, 932, 895, 487 |
| 2 | 391, 408, 466, 895, 487 |
| 17 | 391, 204, 233, 895, 487 |
| 23, 12, 233, 895, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 23 x 12 x 233 x 895 x 487 = 1906013236560
Therefore, the lowest common multiple of 391,816,932,895,487 is 1906013236560.
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.
391 x 816 x 932 x 895 x 487 = 129608900086080
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.
391 : 1, 17, 23, 391
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
932 : 1, 2, 4, 233, 466, 932
895 : 1, 5, 179, 895
487 : 1, 487
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,816,932,895,487, is 1.
Now, the common factors can be found like this.
391:17x 23
816:2x 2x 2x 2x 3x 17
932:2x 2x 233
895:5x 179
487:487
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 17 = 68
Therefore, the value for common factors is 68.
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 = 129608900086080/(1x68)
LCM = 129608900086080/68
LCM = 1906013236560
Thus, we can understand that the LCM of 391,816,932,895,487 is 1906013236560.
