Given numbers are 985,813,394,271,808
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,813,394,271,808 is 647050440.
Find LCM of 985,813,394,271,808 with Prime Factorization
| 2 | 985, 813, 394, 271, 808 |
| 197 | 985, 813, 197, 271, 404 |
| 271 | 5, 813, 1, 271, 404 |
| 5, 3, 1, 1, 404 |
Multiply the prime numbers at the bottom and the left side.
2 x 197 x 271 x 5 x 3 x 1 x 1 x 404 = 647050440
Therefore, the lowest common multiple of 985,813,394,271,808 is 647050440.
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.
985 x 813 x 394 x 271 x 808 = 69088163680560
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.
985 : 1, 5, 197, 985
813 : 1, 3, 271, 813
394 : 1, 2, 197, 394
271 : 1, 271
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,813,394,271,808, is 1.
Now, the common factors can be found like this.
985:5x 197
813:3x 271
394:2x 197
271:271
808:2x 2x 2x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 197x 271 = 106774
Therefore, the value for common factors is 106774.
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 = 69088163680560/(1x106774)
LCM = 69088163680560/106774
LCM = 647050440
Thus, we can understand that the LCM of 985,813,394,271,808 is 647050440.
