The LCM of 904,408,311,438,561 is 11513690232.
Find LCM of 904,408,311,438,561 with Prime Factorization
| 2 | 904, 408, 311, 438, 561 |
| 2 | 452, 204, 311, 219, 561 |
| 2 | 226, 102, 311, 219, 561 |
| 3 | 113, 51, 311, 219, 561 |
| 17 | 113, 17, 311, 73, 187 |
| 113, 1, 311, 73, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 113 x 1 x 311 x 73 x 11 = 11513690232
Therefore, the lowest common multiple of 904,408,311,438,561 is 11513690232.
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.
904 x 408 x 311 x 438 x 561 = 28185513687936
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
311 : 1, 311
438 : 1, 2, 3, 6, 73, 146, 219, 438
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,408,311,438,561, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
408:2x 2x 2x 3x 17
311:311
438:2x 3x 73
561:3x 11x 17
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 3x 3x 17 = 2448
Therefore, the value for common factors is 2448.
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 = 28185513687936/(1x2448)
LCM = 28185513687936/2448
LCM = 11513690232
Thus, we can understand that the LCM of 904,408,311,438,561 is 11513690232.
