Given numbers are 162,381,801,663,538
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 162,381,801,663,538 is 108856231614.
Find LCM of 162,381,801,663,538 with Prime Factorization
| 2 | 162, 381, 801, 663, 538 |
| 3 | 81, 381, 801, 663, 269 |
| 3 | 27, 127, 267, 221, 269 |
| 9, 127, 89, 221, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 9 x 127 x 89 x 221 x 269 = 108856231614
Therefore, the lowest common multiple of 162,381,801,663,538 is 108856231614.
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 381 x 801 x 663 x 538 = 17634709521468
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
381 : 1, 3, 127, 381
801 : 1, 3, 9, 89, 267, 801
663 : 1, 3, 13, 17, 39, 51, 221, 663
538 : 1, 2, 269, 538
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,381,801,663,538, is 1.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
381:3x 127
801:3x 3x 89
663:3x 13x 17
538:2x 269
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 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 17634709521468/(1x162)
LCM = 17634709521468/162
LCM = 108856231614
Thus, we can understand that the LCM of 162,381,801,663,538 is 108856231614.
