Given numbers are 217,682,664,558
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,682,664,558 is 14264712.
Find LCM of 217,682,664,558 with Prime Factorization
| 2 | 217, 682, 664, 558 |
| 31 | 217, 341, 332, 279 |
| 7, 11, 332, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 7 x 11 x 332 x 9 = 14264712
Therefore, the lowest common multiple of 217,682,664,558 is 14264712.
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.
217 x 682 x 664 x 558 = 54833552928
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.
217 : 1, 7, 31, 217
682 : 1, 2, 11, 22, 31, 62, 341, 682
664 : 1, 2, 4, 8, 83, 166, 332, 664
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,682,664,558, is 1.
Now, the common factors can be found like this.
217:7x 31
682:2x 11x 31
664:2x 2x 2x 83
558:2x 3x 3x 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 31x 31 = 3844
Therefore, the value for common factors is 3844.
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 = 54833552928/(1x3844)
LCM = 54833552928/3844
LCM = 14264712
Thus, we can understand that the LCM of 217,682,664,558 is 14264712.
