Given numbers are 834,634,614,720,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,634,614,720,431 is 4197804459120.
Find LCM of 834,634,614,720,431 with Prime Factorization
| 2 | 834, 634, 614, 720, 431 |
| 3 | 417, 317, 307, 360, 431 |
| 139, 317, 307, 120, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 139 x 317 x 307 x 120 x 431 = 4197804459120
Therefore, the lowest common multiple of 834,634,614,720,431 is 4197804459120.
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.
834 x 634 x 614 x 720 x 431 = 100747307018880
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
634 : 1, 2, 317, 634
614 : 1, 2, 307, 614
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,634,614,720,431, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
634:2x 317
614:2x 307
720:2x 2x 2x 2x 3x 3x 5
431:431
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 100747307018880/(1x24)
LCM = 100747307018880/24
LCM = 4197804459120
Thus, we can understand that the LCM of 834,634,614,720,431 is 4197804459120.
