Given numbers are 785,988,361,806,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,988,361,806,857 is 391491843340.
Find LCM of 785,988,361,806,857 with Prime Factorization
| 2 | 785, 988, 361, 806, 857 |
| 13 | 785, 494, 361, 403, 857 |
| 19 | 785, 38, 361, 31, 857 |
| 785, 2, 19, 31, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 785 x 2 x 19 x 31 x 857 = 391491843340
Therefore, the lowest common multiple of 785,988,361,806,857 is 391491843340.
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.
785 x 988 x 361 x 806 x 857 = 193396970609960
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.
785 : 1, 5, 157, 785
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
361 : 1, 19, 361
806 : 1, 2, 13, 26, 31, 62, 403, 806
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,988,361,806,857, is 1.
Now, the common factors can be found like this.
785:5x 157
988:2x 2x 13x 19
361:19x 19
806:2x 13x 31
857:857
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 19 = 494
Therefore, the value for common factors is 494.
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 = 193396970609960/(1x494)
LCM = 193396970609960/494
LCM = 391491843340
Thus, we can understand that the LCM of 785,988,361,806,857 is 391491843340.
