Given numbers are 820,489,547,878,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,489,547,878,580 is 2792367379860.
Find LCM of 820,489,547,878,580 with Prime Factorization
| 2 | 820, 489, 547, 878, 580 |
| 2 | 410, 489, 547, 439, 290 |
| 5 | 205, 489, 547, 439, 145 |
| 41, 489, 547, 439, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 41 x 489 x 547 x 439 x 29 = 2792367379860
Therefore, the lowest common multiple of 820,489,547,878,580 is 2792367379860.
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.
820 x 489 x 547 x 878 x 580 = 111694695194400
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
489 : 1, 3, 163, 489
547 : 1, 547
878 : 1, 2, 439, 878
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,489,547,878,580, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
489:3x 163
547:547
878:2x 439
580:2x 2x 5x 29
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 5 = 40
Therefore, the value for common factors is 40.
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 = 111694695194400/(1x40)
LCM = 111694695194400/40
LCM = 2792367379860
Thus, we can understand that the LCM of 820,489,547,878,580 is 2792367379860.
