Given numbers are 396,543,686,382
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,543,686,382 is 4695709788.
Find LCM of 396,543,686,382 with Prime Factorization
| 2 | 396, 543, 686, 382 |
| 3 | 198, 543, 343, 191 |
| 66, 181, 343, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 66 x 181 x 343 x 191 = 4695709788
Therefore, the lowest common multiple of 396,543,686,382 is 4695709788.
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 543 x 686 x 382 = 56348517456
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
543 : 1, 3, 181, 543
686 : 1, 2, 7, 14, 49, 98, 343, 686
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,543,686,382, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
543:3x 181
686:2x 7x 7x 7
382:2x 191
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 = 56348517456/(1x12)
LCM = 56348517456/12
LCM = 4695709788
Thus, we can understand that the LCM of 396,543,686,382 is 4695709788.
