Given numbers are 396,687,223,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,687,223,308 is 141557724.
Find LCM of 396,687,223,308 with Prime Factorization
| 2 | 396, 687, 223, 308 |
| 2 | 198, 687, 223, 154 |
| 3 | 99, 687, 223, 77 |
| 11 | 33, 229, 223, 77 |
| 3, 229, 223, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 3 x 229 x 223 x 7 = 141557724
Therefore, the lowest common multiple of 396,687,223,308 is 141557724.
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 687 x 223 x 308 = 18685619568
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
687 : 1, 3, 229, 687
223 : 1, 223
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,687,223,308, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
687:3x 229
223:223
308:2x 2x 7x 11
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 18685619568/(1x132)
LCM = 18685619568/132
LCM = 141557724
Thus, we can understand that the LCM of 396,687,223,308 is 141557724.
