Given numbers are 792,308,904,205
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 792,308,904,205 is 128426760.
Find LCM of 792,308,904,205 with Prime Factorization
| 2 | 792, 308, 904, 205 |
| 2 | 396, 154, 452, 205 |
| 2 | 198, 77, 226, 205 |
| 11 | 99, 77, 113, 205 |
| 9, 7, 113, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 9 x 7 x 113 x 205 = 128426760
Therefore, the lowest common multiple of 792,308,904,205 is 128426760.
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.
792 x 308 x 904 x 205 = 45206219520
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.
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
904 : 1, 2, 4, 8, 113, 226, 452, 904
205 : 1, 5, 41, 205
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,308,904,205, is 1.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
308:2x 2x 7x 11
904:2x 2x 2x 113
205:5x 41
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 11 = 352
Therefore, the value for common factors is 352.
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 = 45206219520/(1x352)
LCM = 45206219520/352
LCM = 128426760
Thus, we can understand that the LCM of 792,308,904,205 is 128426760.
