Given numbers are 591,990,858,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 591,990,858,803 is 185083470.
Find LCM of 591,990,858,803 with Prime Factorization
| 2 | 591, 990, 858, 803 |
| 3 | 591, 495, 429, 803 |
| 11 | 197, 165, 143, 803 |
| 197, 15, 13, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 197 x 15 x 13 x 73 = 185083470
Therefore, the lowest common multiple of 591,990,858,803 is 185083470.
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.
591 x 990 x 858 x 803 = 403111797660
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.
591 : 1, 3, 197, 591
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 591,990,858,803, is 1.
Now, the common factors can be found like this.
591:3x 197
990:2x 3x 3x 5x 11
858:2x 3x 11x 13
803:11x 73
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 11x 11 = 2178
Therefore, the value for common factors is 2178.
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 = 403111797660/(1x2178)
LCM = 403111797660/2178
LCM = 185083470
Thus, we can understand that the LCM of 591,990,858,803 is 185083470.
