Given numbers are 993,642,908,591
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 993,642,908,591 is 19005753876.
Find LCM of 993,642,908,591 with Prime Factorization
| 2 | 993, 642, 908, 591 |
| 3 | 993, 321, 454, 591 |
| 331, 107, 454, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 331 x 107 x 454 x 197 = 19005753876
Therefore, the lowest common multiple of 993,642,908,591 is 19005753876.
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.
993 x 642 x 908 x 591 = 342103569768
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.
993 : 1, 3, 331, 993
642 : 1, 2, 3, 6, 107, 214, 321, 642
908 : 1, 2, 4, 227, 454, 908
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,642,908,591, is 1.
Now, the common factors can be found like this.
993:3x 331
642:2x 3x 107
908:2x 2x 227
591:3x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 342103569768/(1x18)
LCM = 342103569768/18
LCM = 19005753876
Thus, we can understand that the LCM of 993,642,908,591 is 19005753876.
