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 8,060,305, 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 | 8,060,305 | |
| -1 | -8,060,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,060,305.
Example:
1 x 8,060,305 = 8,060,305
and
-1 x -8,060,305 = 8,060,305
Notice both answers equal 8,060,305
With that explanation out of the way, let's continue. Next, we take the number 8,060,305 and divide it by 2:
8,060,305 ÷ 2 = 4,030,152.5
If the quotient is a whole number, then 2 and 4,030,152.5 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 | 8,060,305 | |
| -1 | -8,060,305 |
Now, we try dividing 8,060,305 by 3:
8,060,305 ÷ 3 = 2,686,768.3333
If the quotient is a whole number, then 3 and 2,686,768.3333 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 | 8,060,305 | |
| -1 | -8,060,305 |
Let's try dividing by 4:
8,060,305 ÷ 4 = 2,015,076.25
If the quotient is a whole number, then 4 and 2,015,076.25 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 | 8,060,305 | |
| -1 | 8,060,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 101 | 505 | 1,111 | 1,451 | 5,555 | 7,255 | 15,961 | 79,805 | 146,551 | 732,755 | 1,612,061 | 8,060,305 |
| -1 | -5 | -11 | -55 | -101 | -505 | -1,111 | -1,451 | -5,555 | -7,255 | -15,961 | -79,805 | -146,551 | -732,755 | -1,612,061 | -8,060,305 |
