Given numbers are 683,786,328,676,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 683,786,328,676,815 is 12126386636520.
Find LCM of 683,786,328,676,815 with Prime Factorization
| 2 | 683, 786, 328, 676, 815 |
| 2 | 683, 393, 164, 338, 815 |
| 683, 393, 82, 169, 815 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 683 x 393 x 82 x 169 x 815 = 12126386636520
Therefore, the lowest common multiple of 683,786,328,676,815 is 12126386636520.
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.
683 x 786 x 328 x 676 x 815 = 97011093092160
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.
683 : 1, 683
786 : 1, 2, 3, 6, 131, 262, 393, 786
328 : 1, 2, 4, 8, 41, 82, 164, 328
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 683,786,328,676,815, is 1.
Now, the common factors can be found like this.
683:683
786:2x 3x 131
328:2x 2x 2x 41
676:2x 2x 13x 13
815:5x 163
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 2 = 8
Therefore, the value for common factors is 8.
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 = 97011093092160/(1x8)
LCM = 97011093092160/8
LCM = 12126386636520
Thus, we can understand that the LCM of 683,786,328,676,815 is 12126386636520.
