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 40,295,609, 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 | 40,295,609 | |
| -1 | -40,295,609 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,295,609.
Example:
1 x 40,295,609 = 40,295,609
and
-1 x -40,295,609 = 40,295,609
Notice both answers equal 40,295,609
With that explanation out of the way, let's continue. Next, we take the number 40,295,609 and divide it by 2:
40,295,609 ÷ 2 = 20,147,804.5
If the quotient is a whole number, then 2 and 20,147,804.5 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 | 40,295,609 | |
| -1 | -40,295,609 |
Now, we try dividing 40,295,609 by 3:
40,295,609 ÷ 3 = 13,431,869.6667
If the quotient is a whole number, then 3 and 13,431,869.6667 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 | 40,295,609 | |
| -1 | -40,295,609 |
Let's try dividing by 4:
40,295,609 ÷ 4 = 10,073,902.25
If the quotient is a whole number, then 4 and 10,073,902.25 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 | 40,295,609 | |
| -1 | 40,295,609 |
If you did it right, you will end up with this table:
| 1 | 23 | 67 | 79 | 331 | 1,541 | 1,817 | 5,293 | 7,613 | 22,177 | 26,149 | 121,739 | 510,071 | 601,427 | 1,751,983 | 40,295,609 |
| -1 | -23 | -67 | -79 | -331 | -1,541 | -1,817 | -5,293 | -7,613 | -22,177 | -26,149 | -121,739 | -510,071 | -601,427 | -1,751,983 | -40,295,609 |
