Given numbers are 813,793,780,427
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,793,780,427 is 90259260.
Find LCM of 813,793,780,427 with Prime Factorization
| 3 | 813, 793, 780, 427 |
| 13 | 271, 793, 260, 427 |
| 61 | 271, 61, 20, 427 |
| 271, 1, 20, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 61 x 271 x 1 x 20 x 7 = 90259260
Therefore, the lowest common multiple of 813,793,780,427 is 90259260.
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.
813 x 793 x 780 x 427 = 214726779540
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.
813 : 1, 3, 271, 813
793 : 1, 13, 61, 793
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
427 : 1, 7, 61, 427
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,793,780,427, is 1.
Now, the common factors can be found like this.
813:3x 271
793:13x 61
780:2x 2x 3x 5x 13
427:7x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 61 = 2379
Therefore, the value for common factors is 2379.
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 = 214726779540/(1x2379)
LCM = 214726779540/2379
LCM = 90259260
Thus, we can understand that the LCM of 813,793,780,427 is 90259260.
