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 8,261,485, 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 | 8,261,485 | |
| -1 | -8,261,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,261,485.
Example:
1 x 8,261,485 = 8,261,485
and
-1 x -8,261,485 = 8,261,485
Notice both answers equal 8,261,485
With that explanation out of the way, let's continue. Next, we take the number 8,261,485 and divide it by 2:
8,261,485 ÷ 2 = 4,130,742.5
If the quotient is a whole number, then 2 and 4,130,742.5 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 | 8,261,485 | |
| -1 | -8,261,485 |
Now, we try dividing 8,261,485 by 3:
8,261,485 ÷ 3 = 2,753,828.3333
If the quotient is a whole number, then 3 and 2,753,828.3333 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 | 8,261,485 | |
| -1 | -8,261,485 |
Let's try dividing by 4:
8,261,485 ÷ 4 = 2,065,371.25
If the quotient is a whole number, then 4 and 2,065,371.25 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 | 8,261,485 | |
| -1 | 8,261,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 199 | 361 | 437 | 995 | 1,805 | 2,185 | 3,781 | 4,577 | 8,303 | 18,905 | 22,885 | 41,515 | 71,839 | 86,963 | 359,195 | 434,815 | 1,652,297 | 8,261,485 |
| -1 | -5 | -19 | -23 | -95 | -115 | -199 | -361 | -437 | -995 | -1,805 | -2,185 | -3,781 | -4,577 | -8,303 | -18,905 | -22,885 | -41,515 | -71,839 | -86,963 | -359,195 | -434,815 | -1,652,297 | -8,261,485 |
