Given numbers are 676,206,676,822,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,206,676,822,638 is 9128857452.
Find LCM of 676,206,676,822,638 with Prime Factorization
| 2 | 676, 206, 676, 822, 638 |
| 2 | 338, 103, 338, 411, 319 |
| 13 | 169, 103, 169, 411, 319 |
| 13 | 13, 103, 13, 411, 319 |
| 1, 103, 1, 411, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 13 x 1 x 103 x 1 x 411 x 319 = 9128857452
Therefore, the lowest common multiple of 676,206,676,822,638 is 9128857452.
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.
676 x 206 x 676 x 822 x 638 = 49368861100416
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
206 : 1, 2, 103, 206
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
822 : 1, 2, 3, 6, 137, 274, 411, 822
638 : 1, 2, 11, 22, 29, 58, 319, 638
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,206,676,822,638, is 2.
Now, the common factors can be found like this.
676:2x 2x 13x 13
206:2x 103
676:2x 2x 13x 13
822:2x 3x 137
638:2x 11x 29
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 13x 13 = 2704
Therefore, the value for common factors is 2704.
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 = 49368861100416/(2x2704)
LCM = 49368861100416/5408
LCM = 9128857452
Thus, we can understand that the LCM of 676,206,676,822,638 is 9128857452.
