Given numbers are 398,645,463,522,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,645,463,522,806 is 4167235810530.
Find LCM of 398,645,463,522,806 with Prime Factorization
| 2 | 398, 645, 463, 522, 806 |
| 3 | 199, 645, 463, 261, 403 |
| 199, 215, 463, 87, 403 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 199 x 215 x 463 x 87 x 403 = 4167235810530
Therefore, the lowest common multiple of 398,645,463,522,806 is 4167235810530.
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 645 x 463 x 522 x 806 = 50006829726360
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
645 : 1, 3, 5, 15, 43, 129, 215, 645
463 : 1, 463
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,645,463,522,806, is 1.
Now, the common factors can be found like this.
398:2x 199
645:3x 5x 43
463:463
522:2x 3x 3x 29
806:2x 13x 31
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 3 = 12
Therefore, the value for common factors is 12.
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 = 50006829726360/(1x12)
LCM = 50006829726360/12
LCM = 4167235810530
Thus, we can understand that the LCM of 398,645,463,522,806 is 4167235810530.
