Find LCM of 162,638,486,311,661 with Prime Factorization
| 2 | 162, 638, 486, 311, 661 |
| 3 | 81, 319, 243, 311, 661 |
| 3 | 27, 319, 81, 311, 661 |
| 3 | 9, 319, 27, 311, 661 |
| 3 | 3, 319, 9, 311, 661 |
| 1, 319, 3, 311, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 1 x 319 x 3 x 311 x 661 = 31870494414
Therefore, the lowest common multiple of 162,638,486,311,661 is 31870494414.
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.
162 x 638 x 486 x 311 x 661 = 10326040190136
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.
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
638 : 1, 2, 11, 22, 29, 58, 319, 638
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
311 : 1, 311
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,638,486,311,661, is 1.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
638:2x 11x 29
486:2x 3x 3x 3x 3x 3
311:311
661:661
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 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 10326040190136/(1x324)
LCM = 10326040190136/324
LCM = 31870494414
Thus, we can understand that the LCM of 162,638,486,311,661 is 31870494414.
