Given numbers are 682,768,620,634,344
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,768,620,634,344 is 17848976640.
Find LCM of 682,768,620,634,344 with Prime Factorization
| 2 | 682, 768, 620, 634, 344 |
| 2 | 341, 384, 310, 317, 172 |
| 2 | 341, 192, 155, 317, 86 |
| 31 | 341, 96, 155, 317, 43 |
| 11, 96, 5, 317, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 31 x 11 x 96 x 5 x 317 x 43 = 17848976640
Therefore, the lowest common multiple of 682,768,620,634,344 is 17848976640.
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.
682 x 768 x 620 x 634 x 344 = 70824739307520
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
634 : 1, 2, 317, 634
344 : 1, 2, 4, 8, 43, 86, 172, 344
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,768,620,634,344, is 2.
Now, the common factors can be found like this.
682:2x 11x 31
768:2x 2x 2x 2x 2x 2x 2x 2x 3
620:2x 2x 5x 31
634:2x 317
344:2x 2x 2x 43
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 31 = 1984
Therefore, the value for common factors is 1984.
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 = 70824739307520/(2x1984)
LCM = 70824739307520/3968
LCM = 17848976640
Thus, we can understand that the LCM of 682,768,620,634,344 is 17848976640.
