Given numbers are 897,388,897,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,388,897,847 is 294786492.
Find LCM of 897,388,897,847 with Prime Factorization
| 3 | 897, 388, 897, 847 |
| 13 | 299, 388, 299, 847 |
| 23 | 23, 388, 23, 847 |
| 1, 388, 1, 847 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 23 x 1 x 388 x 1 x 847 = 294786492
Therefore, the lowest common multiple of 897,388,897,847 is 294786492.
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 388 x 897 x 847 = 264423483324
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
388 : 1, 2, 4, 97, 194, 388
897 : 1, 3, 13, 23, 39, 69, 299, 897
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,388,897,847, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
388:2x 2x 97
897:3x 13x 23
847:7x 11x 11
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 = 264423483324/(1x897)
LCM = 264423483324/897
LCM = 294786492
Thus, we can understand that the LCM of 897,388,897,847 is 294786492.
