Given numbers are 398,838,115,799
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,838,115,799 is 15322926370.
Find LCM of 398,838,115,799 with Prime Factorization
| 2 | 398, 838, 115, 799 |
| 199, 419, 115, 799 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 419 x 115 x 799 = 15322926370
Therefore, the lowest common multiple of 398,838,115,799 is 15322926370.
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.
398 x 838 x 115 x 799 = 30645852740
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.
398 : 1, 2, 199, 398
838 : 1, 2, 419, 838
115 : 1, 5, 23, 115
799 : 1, 17, 47, 799
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,838,115,799, is 1.
Now, the common factors can be found like this.
398:2x 199
838:2x 419
115:5x 23
799:17x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 30645852740/(1x2)
LCM = 30645852740/2
LCM = 15322926370
Thus, we can understand that the LCM of 398,838,115,799 is 15322926370.
