Given numbers are 489,828,206,638,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,828,206,638,788 is 873598893156.
Find LCM of 489,828,206,638,788 with Prime Factorization
| 2 | 489, 828, 206, 638, 788 |
| 2 | 489, 414, 103, 319, 394 |
| 3 | 489, 207, 103, 319, 197 |
| 163, 69, 103, 319, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 163 x 69 x 103 x 319 x 197 = 873598893156
Therefore, the lowest common multiple of 489,828,206,638,788 is 873598893156.
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.
489 x 828 x 206 x 638 x 788 = 41932746871488
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.
489 : 1, 3, 163, 489
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
206 : 1, 2, 103, 206
638 : 1, 2, 11, 22, 29, 58, 319, 638
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,828,206,638,788, is 1.
Now, the common factors can be found like this.
489:3x 163
828:2x 2x 3x 3x 23
206:2x 103
638:2x 11x 29
788:2x 2x 197
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 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 41932746871488/(1x48)
LCM = 41932746871488/48
LCM = 873598893156
Thus, we can understand that the LCM of 489,828,206,638,788 is 873598893156.
