Given numbers are 531,814,418,810
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 531,814,418,810 is 369560070.
Find LCM of 531,814,418,810 with Prime Factorization
| 2 | 531, 814, 418, 810 |
| 3 | 531, 407, 209, 405 |
| 3 | 177, 407, 209, 135 |
| 11 | 59, 407, 209, 45 |
| 59, 37, 19, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 59 x 37 x 19 x 45 = 369560070
Therefore, the lowest common multiple of 531,814,418,810 is 369560070.
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.
531 x 814 x 418 x 810 = 146345787720
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.
531 : 1, 3, 9, 59, 177, 531
814 : 1, 2, 11, 22, 37, 74, 407, 814
418 : 1, 2, 11, 19, 22, 38, 209, 418
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,814,418,810, is 1.
Now, the common factors can be found like this.
531:3x 3x 59
814:2x 11x 37
418:2x 11x 19
810:2x 3x 3x 3x 3x 5
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 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 146345787720/(1x396)
LCM = 146345787720/396
LCM = 369560070
Thus, we can understand that the LCM of 531,814,418,810 is 369560070.
