Given numbers are 389,806,725,665,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,806,725,665,845 is 393022707350.
Find LCM of 389,806,725,665,845 with Prime Factorization
| 5 | 389, 806, 725, 665, 845 |
| 13 | 389, 806, 145, 133, 169 |
| 389, 62, 145, 133, 13 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 389 x 62 x 145 x 133 x 13 = 393022707350
Therefore, the lowest common multiple of 389,806,725,665,845 is 393022707350.
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.
389 x 806 x 725 x 665 x 845 = 127732379888750
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.
389 : 1, 389
806 : 1, 2, 13, 26, 31, 62, 403, 806
725 : 1, 5, 25, 29, 145, 725
665 : 1, 5, 7, 19, 35, 95, 133, 665
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,806,725,665,845, is 1.
Now, the common factors can be found like this.
389:389
806:2x 13x 31
725:5x 5x 29
665:5x 7x 19
845:5x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 13 = 325
Therefore, the value for common factors is 325.
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 = 127732379888750/(1x325)
LCM = 127732379888750/325
LCM = 393022707350
Thus, we can understand that the LCM of 389,806,725,665,845 is 393022707350.
