The LCM of 704,755,792,399 is 636229440.
Find LCM of 704,755,792,399 with Prime Factorization
| 2 | 704, 755, 792, 399 |
| 2 | 352, 755, 396, 399 |
| 2 | 176, 755, 198, 399 |
| 3 | 88, 755, 99, 399 |
| 11 | 88, 755, 33, 133 |
| 8, 755, 3, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 8 x 755 x 3 x 133 = 636229440
Therefore, the lowest common multiple of 704,755,792,399 is 636229440.
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.
704 x 755 x 792 x 399 = 167964572160
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
755 : 1, 5, 151, 755
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
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,755,792,399, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
755:5x 151
792:2x 2x 2x 3x 3x 11
399:3x 7x 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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 167964572160/(1x264)
LCM = 167964572160/264
LCM = 636229440
Thus, we can understand that the LCM of 704,755,792,399 is 636229440.
