Find LCM of 989,903,858,468,986 with Prime Factorization
| 2 | 989, 903, 858, 468, 986 |
| 3 | 989, 903, 429, 234, 493 |
| 13 | 989, 301, 143, 78, 493 |
| 43 | 989, 301, 11, 6, 493 |
| 23, 7, 11, 6, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 43 x 23 x 7 x 11 x 6 x 493 = 17570324772
Therefore, the lowest common multiple of 989,903,858,468,986 is 17570324772.
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.
989 x 903 x 858 x 468 x 986 = 353585215711728
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.
989 : 1, 23, 43, 989
903 : 1, 3, 7, 21, 43, 129, 301, 903
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,903,858,468,986, is 1.
Now, the common factors can be found like this.
989:23x 43
903:3x 7x 43
858:2x 3x 11x 13
468:2x 2x 3x 3x 13
986:2x 17x 29
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 13x 43 = 20124
Therefore, the value for common factors is 20124.
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 = 353585215711728/(1x20124)
LCM = 353585215711728/20124
LCM = 17570324772
Thus, we can understand that the LCM of 989,903,858,468,986 is 17570324772.
