Given numbers are 328,172,981,809,158
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 328,172,981,809,158 is 884274129864.
Find LCM of 328,172,981,809,158 with Prime Factorization
| 2 | 328, 172, 981, 809, 158 |
| 2 | 164, 86, 981, 809, 79 |
| 82, 43, 981, 809, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 82 x 43 x 981 x 809 x 79 = 884274129864
Therefore, the lowest common multiple of 328,172,981,809,158 is 884274129864.
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.
328 x 172 x 981 x 809 x 158 = 7074193038912
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
172 : 1, 2, 4, 43, 86, 172
981 : 1, 3, 9, 109, 327, 981
809 : 1, 809
158 : 1, 2, 79, 158
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,172,981,809,158, is 1.
Now, the common factors can be found like this.
328:2x 2x 2x 41
172:2x 2x 43
981:3x 3x 109
809:809
158:2x 79
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 2 = 8
Therefore, the value for common factors is 8.
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 = 7074193038912/(1x8)
LCM = 7074193038912/8
LCM = 884274129864
Thus, we can understand that the LCM of 328,172,981,809,158 is 884274129864.
