Given numbers are 810,279,771,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,279,771,806 is 83892510.
Find LCM of 810,279,771,806 with Prime Factorization
| 2 | 810, 279, 771, 806 |
| 3 | 405, 279, 771, 403 |
| 3 | 135, 93, 257, 403 |
| 31 | 45, 31, 257, 403 |
| 45, 1, 257, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 31 x 45 x 1 x 257 x 13 = 83892510
Therefore, the lowest common multiple of 810,279,771,806 is 83892510.
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 279 x 771 x 806 = 140436061740
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
279 : 1, 3, 9, 31, 93, 279
771 : 1, 3, 257, 771
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,279,771,806, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
279:3x 3x 31
771:3x 257
806:2x 13x 31
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 3x 31 = 1674
Therefore, the value for common factors is 1674.
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 = 140436061740/(1x1674)
LCM = 140436061740/1674
LCM = 83892510
Thus, we can understand that the LCM of 810,279,771,806 is 83892510.
