Given numbers are 814,687,576,530,903
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,687,576,530,903 is 4282178281920.
Find LCM of 814,687,576,530,903 with Prime Factorization
| 2 | 814, 687, 576, 530, 903 |
| 3 | 407, 687, 288, 265, 903 |
| 407, 229, 96, 265, 301 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 407 x 229 x 96 x 265 x 301 = 4282178281920
Therefore, the lowest common multiple of 814,687,576,530,903 is 4282178281920.
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 687 x 576 x 530 x 903 = 154158418149120
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
687 : 1, 3, 229, 687
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
530 : 1, 2, 5, 10, 53, 106, 265, 530
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,687,576,530,903, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
687:3x 229
576:2x 2x 2x 2x 2x 2x 3x 3
530:2x 5x 53
903:3x 7x 43
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 154158418149120/(1x36)
LCM = 154158418149120/36
LCM = 4282178281920
Thus, we can understand that the LCM of 814,687,576,530,903 is 4282178281920.
