Given numbers are 818,899,810,808,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 818,899,810,808,644 is 19372035657240.
Find LCM of 818,899,810,808,644 with Prime Factorization
| 2 | 818, 899, 810, 808, 644 |
| 2 | 409, 899, 405, 404, 322 |
| 409, 899, 405, 202, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 409 x 899 x 405 x 202 x 161 = 19372035657240
Therefore, the lowest common multiple of 818,899,810,808,644 is 19372035657240.
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.
818 x 899 x 810 x 808 x 644 = 309952570515840
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.
818 : 1, 2, 409, 818
899 : 1, 29, 31, 899
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
808 : 1, 2, 4, 8, 101, 202, 404, 808
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,899,810,808,644, is 1.
Now, the common factors can be found like this.
818:2x 409
899:29x 31
810:2x 3x 3x 3x 3x 5
808:2x 2x 2x 101
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 309952570515840/(1x16)
LCM = 309952570515840/16
LCM = 19372035657240
Thus, we can understand that the LCM of 818,899,810,808,644 is 19372035657240.
