Given numbers are 799,811,861,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 799,811,861,287 is 557918529.
Find LCM of 799,811,861,287 with Prime Factorization
| 7 | 799, 811, 861, 287 |
| 41 | 799, 811, 123, 41 |
| 799, 811, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 41 x 799 x 811 x 3 x 1 = 557918529
Therefore, the lowest common multiple of 799,811,861,287 is 557918529.
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.
799 x 811 x 861 x 287 = 160122617823
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.
799 : 1, 17, 47, 799
811 : 1, 811
861 : 1, 3, 7, 21, 41, 123, 287, 861
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 799,811,861,287, is 1.
Now, the common factors can be found like this.
799:17x 47
811:811
861:3x 7x 41
287:7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 41 = 287
Therefore, the value for common factors is 287.
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 = 160122617823/(1x287)
LCM = 160122617823/287
LCM = 557918529
Thus, we can understand that the LCM of 799,811,861,287 is 557918529.
