Given numbers are 357,815,693,605
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 357,815,693,605 is 105616665.
Find LCM of 357,815,693,605 with Prime Factorization
| 3 | 357, 815, 693, 605 |
| 5 | 119, 815, 231, 605 |
| 7 | 119, 163, 231, 121 |
| 11 | 17, 163, 33, 121 |
| 17, 163, 3, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 11 x 17 x 163 x 3 x 11 = 105616665
Therefore, the lowest common multiple of 357,815,693,605 is 105616665.
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.
357 x 815 x 693 x 605 = 121987248075
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
815 : 1, 5, 163, 815
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,815,693,605, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
815:5x 163
693:3x 3x 7x 11
605:5x 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.
3x 5x 7x 11 = 1155
Therefore, the value for common factors is 1155.
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 = 121987248075/(1x1155)
LCM = 121987248075/1155
LCM = 105616665
Thus, we can understand that the LCM of 357,815,693,605 is 105616665.
