Given numbers are 676,607,398,845,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,607,398,845,819 is 25721661420.
Find LCM of 676,607,398,845,819 with Prime Factorization
| 2 | 676, 607, 398, 845, 819 |
| 13 | 338, 607, 199, 845, 819 |
| 13 | 26, 607, 199, 65, 63 |
| 2, 607, 199, 5, 63 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 13 x 2 x 607 x 199 x 5 x 63 = 25721661420
Therefore, the lowest common multiple of 676,607,398,845,819 is 25721661420.
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 607 x 398 x 845 x 819 = 113020980279480
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
607 : 1, 607
398 : 1, 2, 199, 398
845 : 1, 5, 13, 65, 169, 845
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,607,398,845,819, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
607:607
398:2x 199
845:5x 13x 13
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13x 13 = 4394
Therefore, the value for common factors is 4394.
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 = 113020980279480/(1x4394)
LCM = 113020980279480/4394
LCM = 25721661420
Thus, we can understand that the LCM of 676,607,398,845,819 is 25721661420.
