Given numbers are 726,490,682,793,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 726,490,682,793,418 is 83078985990.
Find LCM of 726,490,682,793,418 with Prime Factorization
| 2 | 726, 490, 682, 793, 418 |
| 11 | 363, 245, 341, 793, 209 |
| 33, 245, 31, 793, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 33 x 245 x 31 x 793 x 19 = 83078985990
Therefore, the lowest common multiple of 726,490,682,793,418 is 83078985990.
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.
726 x 490 x 682 x 793 x 418 = 80420458438320
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.
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
682 : 1, 2, 11, 22, 31, 62, 341, 682
793 : 1, 13, 61, 793
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,490,682,793,418, is 1.
Now, the common factors can be found like this.
726:2x 3x 11x 11
490:2x 5x 7x 7
682:2x 11x 31
793:13x 61
418:2x 11x 19
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 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 80420458438320/(1x968)
LCM = 80420458438320/968
LCM = 83078985990
Thus, we can understand that the LCM of 726,490,682,793,418 is 83078985990.
