Given numbers are 396,455,319,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,455,319,806 is 161981820.
Find LCM of 396,455,319,806 with Prime Factorization
| 2 | 396, 455, 319, 806 |
| 11 | 198, 455, 319, 403 |
| 13 | 18, 455, 29, 403 |
| 18, 35, 29, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 18 x 35 x 29 x 31 = 161981820
Therefore, the lowest common multiple of 396,455,319,806 is 161981820.
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.
396 x 455 x 319 x 806 = 46326800520
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
455 : 1, 5, 7, 13, 35, 65, 91, 455
319 : 1, 11, 29, 319
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 396,455,319,806, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
455:5x 7x 13
319:11x 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 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 46326800520/(1x286)
LCM = 46326800520/286
LCM = 161981820
Thus, we can understand that the LCM of 396,455,319,806 is 161981820.
