Find LCM of 405,376,605,448,912 with Prime Factorization
| 2 | 405, 376, 605, 448, 912 |
| 2 | 405, 188, 605, 224, 456 |
| 2 | 405, 94, 605, 112, 228 |
| 2 | 405, 47, 605, 56, 114 |
| 3 | 405, 47, 605, 28, 57 |
| 5 | 135, 47, 605, 28, 19 |
| 27, 47, 121, 28, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 27 x 47 x 121 x 28 x 19 = 19605136320
Therefore, the lowest common multiple of 405,376,605,448,912 is 19605136320.
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.
405 x 376 x 605 x 448 x 912 = 37641861734400
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
376 : 1, 2, 4, 8, 47, 94, 188, 376
605 : 1, 5, 11, 55, 121, 605
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,376,605,448,912, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
376:2x 2x 2x 47
605:5x 11x 11
448:2x 2x 2x 2x 2x 2x 7
912:2x 2x 2x 2x 3x 19
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 2x 2x 2x 2x 2x 3x 5 = 1920
Therefore, the value for common factors is 1920.
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 = 37641861734400/(1x1920)
LCM = 37641861734400/1920
LCM = 19605136320
Thus, we can understand that the LCM of 405,376,605,448,912 is 19605136320.
