Given numbers are 820,393,339,159,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,393,339,159,899 is 1735083610860.
Find LCM of 820,393,339,159,899 with Prime Factorization
| 3 | 820, 393, 339, 159, 899 |
| 820, 131, 113, 53, 899 |
Multiply the prime numbers at the bottom and the left side.
3 x 820 x 131 x 113 x 53 x 899 = 1735083610860
Therefore, the lowest common multiple of 820,393,339,159,899 is 1735083610860.
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.
820 x 393 x 339 x 159 x 899 = 15615752497740
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
393 : 1, 3, 131, 393
339 : 1, 3, 113, 339
159 : 1, 3, 53, 159
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,393,339,159,899, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
393:3x 131
339:3x 113
159:3x 53
899:29x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 15615752497740/(1x9)
LCM = 15615752497740/9
LCM = 1735083610860
Thus, we can understand that the LCM of 820,393,339,159,899 is 1735083610860.
