Given numbers are 989,806,982,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,806,982,930 is 5870891910.
Find LCM of 989,806,982,930 with Prime Factorization
| 2 | 989, 806, 982, 930 |
| 31 | 989, 403, 491, 465 |
| 989, 13, 491, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 989 x 13 x 491 x 15 = 5870891910
Therefore, the lowest common multiple of 989,806,982,930 is 5870891910.
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 806 x 982 x 930 = 727990596840
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
806 : 1, 2, 13, 26, 31, 62, 403, 806
982 : 1, 2, 491, 982
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,806,982,930, is 1.
Now, the common factors can be found like this.
989:23x 43
806:2x 13x 31
982:2x 491
930:2x 3x 5x 31
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 31 = 124
Therefore, the value for common factors is 124.
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 = 727990596840/(1x124)
LCM = 727990596840/124
LCM = 5870891910
Thus, we can understand that the LCM of 989,806,982,930 is 5870891910.
