Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 8,611,757, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 8,611,757 | |
| -1 | -8,611,757 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,611,757.
Example:
1 x 8,611,757 = 8,611,757
and
-1 x -8,611,757 = 8,611,757
Notice both answers equal 8,611,757
With that explanation out of the way, let's continue. Next, we take the number 8,611,757 and divide it by 2:
8,611,757 ÷ 2 = 4,305,878.5
If the quotient is a whole number, then 2 and 4,305,878.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,611,757 | |
| -1 | -8,611,757 |
Now, we try dividing 8,611,757 by 3:
8,611,757 ÷ 3 = 2,870,585.6667
If the quotient is a whole number, then 3 and 2,870,585.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,611,757 | |
| -1 | -8,611,757 |
Let's try dividing by 4:
8,611,757 ÷ 4 = 2,152,939.25
If the quotient is a whole number, then 4 and 2,152,939.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,611,757 | |
| -1 | 8,611,757 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 97 | 679 | 1,067 | 1,153 | 7,469 | 8,071 | 12,683 | 88,781 | 111,841 | 782,887 | 1,230,251 | 8,611,757 |
| -1 | -7 | -11 | -77 | -97 | -679 | -1,067 | -1,153 | -7,469 | -8,071 | -12,683 | -88,781 | -111,841 | -782,887 | -1,230,251 | -8,611,757 |
