Given numbers are 323,243,651,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 323,243,651,285 is 85160565.
Find LCM of 323,243,651,285 with Prime Factorization
| 3 | 323, 243, 651, 285 |
| 19 | 323, 81, 217, 95 |
| 17, 81, 217, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 17 x 81 x 217 x 5 = 85160565
Therefore, the lowest common multiple of 323,243,651,285 is 85160565.
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.
323 x 243 x 651 x 285 = 14562456615
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.
323 : 1, 17, 19, 323
243 : 1, 3, 9, 27, 81, 243
651 : 1, 3, 7, 21, 31, 93, 217, 651
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,243,651,285, is 1.
Now, the common factors can be found like this.
323:17x 19
243:3x 3x 3x 3x 3
651:3x 7x 31
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 19 = 171
Therefore, the value for common factors is 171.
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 = 14562456615/(1x171)
LCM = 14562456615/171
LCM = 85160565
Thus, we can understand that the LCM of 323,243,651,285 is 85160565.
