Given numbers are 684,643,726,574,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,643,726,574,861 is 15273351324.
Find LCM of 684,643,726,574,861 with Prime Factorization
| 2 | 684, 643, 726, 574, 861 |
| 3 | 342, 643, 363, 287, 861 |
| 7 | 114, 643, 121, 287, 287 |
| 41 | 114, 643, 121, 41, 41 |
| 114, 643, 121, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 114 x 643 x 121 x 1 x 1 = 15273351324
Therefore, the lowest common multiple of 684,643,726,574,861 is 15273351324.
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.
684 x 643 x 726 x 574 x 861 = 157804265879568
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
643 : 1, 643
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
574 : 1, 2, 7, 14, 41, 82, 287, 574
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,643,726,574,861, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
643:643
726:2x 3x 11x 11
574:2x 7x 41
861:3x 7x 41
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 3x 3x 7x 41 = 10332
Therefore, the value for common factors is 10332.
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 = 157804265879568/(1x10332)
LCM = 157804265879568/10332
LCM = 15273351324
Thus, we can understand that the LCM of 684,643,726,574,861 is 15273351324.
