Given numbers are 405,272,362,789,867
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,272,362,789,867 is 89147090160.
Find LCM of 405,272,362,789,867 with Prime Factorization
| 2 | 405, 272, 362, 789, 867 |
| 3 | 405, 136, 181, 789, 867 |
| 17 | 135, 136, 181, 263, 289 |
| 135, 8, 181, 263, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 135 x 8 x 181 x 263 x 17 = 89147090160
Therefore, the lowest common multiple of 405,272,362,789,867 is 89147090160.
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.
405 x 272 x 362 x 789 x 867 = 27279009588960
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
362 : 1, 2, 181, 362
789 : 1, 3, 263, 789
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,272,362,789,867, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
272:2x 2x 2x 2x 17
362:2x 181
789:3x 263
867:3x 17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 17 = 306
Therefore, the value for common factors is 306.
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 = 27279009588960/(1x306)
LCM = 27279009588960/306
LCM = 89147090160
Thus, we can understand that the LCM of 405,272,362,789,867 is 89147090160.
