Given numbers are 518,406,480,810
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 518,406,480,810 is 97342560.
Find LCM of 518,406,480,810 with Prime Factorization
| 2 | 518, 406, 480, 810 |
| 3 | 259, 203, 240, 405 |
| 5 | 259, 203, 80, 135 |
| 7 | 259, 203, 16, 27 |
| 37, 29, 16, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 37 x 29 x 16 x 27 = 97342560
Therefore, the lowest common multiple of 518,406,480,810 is 97342560.
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.
518 x 406 x 480 x 810 = 81767750400
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
406 : 1, 2, 7, 14, 29, 58, 203, 406
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,406,480,810, is 2.
Now, the common factors can be found like this.
518:2x 7x 37
406:2x 7x 29
480:2x 2x 2x 2x 2x 3x 5
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 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 81767750400/(2x420)
LCM = 81767750400/840
LCM = 97342560
Thus, we can understand that the LCM of 518,406,480,810 is 97342560.
