Given numbers are 811,729,998,630
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,729,998,630 is 20651279670.
Find LCM of 811,729,998,630 with Prime Factorization
| 2 | 811, 729, 998, 630 |
| 3 | 811, 729, 499, 315 |
| 3 | 811, 243, 499, 105 |
| 811, 81, 499, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 811 x 81 x 499 x 35 = 20651279670
Therefore, the lowest common multiple of 811,729,998,630 is 20651279670.
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.
811 x 729 x 998 x 630 = 371723034060
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.
811 : 1, 811
729 : 1, 3, 9, 27, 81, 243, 729
998 : 1, 2, 499, 998
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,729,998,630, is 1.
Now, the common factors can be found like this.
811:811
729:3x 3x 3x 3x 3x 3
998:2x 499
630:2x 3x 3x 5x 7
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 3 = 18
Therefore, the value for common factors is 18.
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 = 371723034060/(1x18)
LCM = 371723034060/18
LCM = 20651279670
Thus, we can understand that the LCM of 811,729,998,630 is 20651279670.
