Given numbers are 814,811,511,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,811,511,861 is 41492659362.
Find LCM of 814,811,511,861 with Prime Factorization
| 7 | 814, 811, 511, 861 |
| 814, 811, 73, 123 |
Multiply the prime numbers at the bottom and the left side.
7 x 814 x 811 x 73 x 123 = 41492659362
Therefore, the lowest common multiple of 814,811,511,861 is 41492659362.
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.
814 x 811 x 511 x 861 = 290448615534
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
811 : 1, 811
511 : 1, 7, 73, 511
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,811,511,861, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
811:811
511:7x 73
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 290448615534/(1x7)
LCM = 290448615534/7
LCM = 41492659362
Thus, we can understand that the LCM of 814,811,511,861 is 41492659362.
