Given numbers are 486,917,720,115
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 486,917,720,115 is 410009040.
Find LCM of 486,917,720,115 with Prime Factorization
| 2 | 486, 917, 720, 115 |
| 3 | 243, 917, 360, 115 |
| 3 | 81, 917, 120, 115 |
| 5 | 27, 917, 40, 115 |
| 27, 917, 8, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 27 x 917 x 8 x 23 = 410009040
Therefore, the lowest common multiple of 486,917,720,115 is 410009040.
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.
486 x 917 x 720 x 115 = 36900813600
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
917 : 1, 7, 131, 917
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
115 : 1, 5, 23, 115
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,917,720,115, is 1.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
917:7x 131
720:2x 2x 2x 2x 3x 3x 5
115:5x 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 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 36900813600/(1x90)
LCM = 36900813600/90
LCM = 410009040
Thus, we can understand that the LCM of 486,917,720,115 is 410009040.
