Given numbers are 676,806,961,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,806,961,788 is 127978292.
Find LCM of 676,806,961,788 with Prime Factorization
| 2 | 676, 806, 961, 788 |
| 2 | 338, 403, 961, 394 |
| 13 | 169, 403, 961, 197 |
| 31 | 13, 31, 961, 197 |
| 13, 1, 31, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 31 x 13 x 1 x 31 x 197 = 127978292
Therefore, the lowest common multiple of 676,806,961,788 is 127978292.
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 806 x 961 x 788 = 412602013408
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
806 : 1, 2, 13, 26, 31, 62, 403, 806
961 : 1, 31, 961
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,806,961,788, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
806:2x 13x 31
961:31x 31
788:2x 2x 197
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 13x 31 = 3224
Therefore, the value for common factors is 3224.
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 = 412602013408/(1x3224)
LCM = 412602013408/3224
LCM = 127978292
Thus, we can understand that the LCM of 676,806,961,788 is 127978292.
