Given numbers are 897,311,920,481,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,311,920,481,129 is 17753459880.
Find LCM of 897,311,920,481,129 with Prime Factorization
| 3 | 897, 311, 920, 481, 129 |
| 13 | 299, 311, 920, 481, 43 |
| 23 | 23, 311, 920, 37, 43 |
| 1, 311, 40, 37, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 23 x 1 x 311 x 40 x 37 x 43 = 17753459880
Therefore, the lowest common multiple of 897,311,920,481,129 is 17753459880.
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.
897 x 311 x 920 x 481 x 129 = 15924853512360
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
311 : 1, 311
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
481 : 1, 13, 37, 481
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,311,920,481,129, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
311:311
920:2x 2x 2x 5x 23
481:13x 37
129:3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 23 = 897
Therefore, the value for common factors is 897.
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 = 15924853512360/(1x897)
LCM = 15924853512360/897
LCM = 17753459880
Thus, we can understand that the LCM of 897,311,920,481,129 is 17753459880.
