Given numbers are 866,568,416,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 866,568,416,689 is 677821664.
Find LCM of 866,568,416,689 with Prime Factorization
| 2 | 866, 568, 416, 689 |
| 2 | 433, 284, 208, 689 |
| 2 | 433, 142, 104, 689 |
| 13 | 433, 71, 52, 689 |
| 433, 71, 4, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 433 x 71 x 4 x 53 = 677821664
Therefore, the lowest common multiple of 866,568,416,689 is 677821664.
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.
866 x 568 x 416 x 689 = 140986906112
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.
866 : 1, 2, 433, 866
568 : 1, 2, 4, 8, 71, 142, 284, 568
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,568,416,689, is 1.
Now, the common factors can be found like this.
866:2x 433
568:2x 2x 2x 71
416:2x 2x 2x 2x 2x 13
689:13x 53
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 2x 13 = 208
Therefore, the value for common factors is 208.
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 = 140986906112/(1x208)
LCM = 140986906112/208
LCM = 677821664
Thus, we can understand that the LCM of 866,568,416,689 is 677821664.
