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 40,332,305, 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 | 40,332,305 | |
| -1 | -40,332,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,332,305.
Example:
1 x 40,332,305 = 40,332,305
and
-1 x -40,332,305 = 40,332,305
Notice both answers equal 40,332,305
With that explanation out of the way, let's continue. Next, we take the number 40,332,305 and divide it by 2:
40,332,305 ÷ 2 = 20,166,152.5
If the quotient is a whole number, then 2 and 20,166,152.5 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 | 40,332,305 | |
| -1 | -40,332,305 |
Now, we try dividing 40,332,305 by 3:
40,332,305 ÷ 3 = 13,444,101.6667
If the quotient is a whole number, then 3 and 13,444,101.6667 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 | 40,332,305 | |
| -1 | -40,332,305 |
Let's try dividing by 4:
40,332,305 ÷ 4 = 10,083,076.25
If the quotient is a whole number, then 4 and 10,083,076.25 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 | 40,332,305 | |
| -1 | 40,332,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 719 | 863 | 3,595 | 4,315 | 9,347 | 11,219 | 46,735 | 56,095 | 620,497 | 3,102,485 | 8,066,461 | 40,332,305 |
| -1 | -5 | -13 | -65 | -719 | -863 | -3,595 | -4,315 | -9,347 | -11,219 | -46,735 | -56,095 | -620,497 | -3,102,485 | -8,066,461 | -40,332,305 |
