Find LCM of 415,809,660,484 with Prime Factorization
| 2 | 415, 809, 660, 484 |
| 2 | 415, 809, 330, 242 |
| 5 | 415, 809, 165, 121 |
| 11 | 83, 809, 33, 121 |
| 83, 809, 3, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 83 x 809 x 3 x 11 = 487487220
Therefore, the lowest common multiple of 415,809,660,484 is 487487220.
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.
415 x 809 x 660 x 484 = 107247188400
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.
415 : 1, 5, 83, 415
809 : 1, 809
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 415,809,660,484, is 1.
Now, the common factors can be found like this.
415:5x 83
809:809
660:2x 2x 3x 5x 11
484:2x 2x 11x 11
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 107247188400/(1x220)
LCM = 107247188400/220
LCM = 487487220
Thus, we can understand that the LCM of 415,809,660,484 is 487487220.
