Given numbers are 810,831,607,489,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,831,607,489,768 is 2841522197760.
Find LCM of 810,831,607,489,768 with Prime Factorization
| 2 | 810, 831, 607, 489, 768 |
| 3 | 405, 831, 607, 489, 384 |
| 135, 277, 607, 163, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 135 x 277 x 607 x 163 x 128 = 2841522197760
Therefore, the lowest common multiple of 810,831,607,489,768 is 2841522197760.
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.
810 x 831 x 607 x 489 x 768 = 153442198679040
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
831 : 1, 3, 277, 831
607 : 1, 607
489 : 1, 3, 163, 489
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,831,607,489,768, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
831:3x 277
607:607
489:3x 163
768:2x 2x 2x 2x 2x 2x 2x 2x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 153442198679040/(1x54)
LCM = 153442198679040/54
LCM = 2841522197760
Thus, we can understand that the LCM of 810,831,607,489,768 is 2841522197760.
