Given numbers are 382,815,455,862,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 382,815,455,862,489 is 36632021790.
Find LCM of 382,815,455,862,489 with Prime Factorization
| 2 | 382, 815, 455, 862, 489 |
| 5 | 191, 815, 455, 431, 489 |
| 163 | 191, 163, 91, 431, 489 |
| 191, 1, 91, 431, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 163 x 191 x 1 x 91 x 431 x 3 = 36632021790
Therefore, the lowest common multiple of 382,815,455,862,489 is 36632021790.
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.
382 x 815 x 455 x 862 x 489 = 59710195517700
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.
382 : 1, 2, 191, 382
815 : 1, 5, 163, 815
455 : 1, 5, 7, 13, 35, 65, 91, 455
862 : 1, 2, 431, 862
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,815,455,862,489, is 1.
Now, the common factors can be found like this.
382:2x 191
815:5x 163
455:5x 7x 13
862:2x 431
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 163 = 1630
Therefore, the value for common factors is 1630.
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 = 59710195517700/(1x1630)
LCM = 59710195517700/1630
LCM = 36632021790
Thus, we can understand that the LCM of 382,815,455,862,489 is 36632021790.
