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 31,660,465, 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 | 31,660,465 | |
| -1 | -31,660,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,660,465.
Example:
1 x 31,660,465 = 31,660,465
and
-1 x -31,660,465 = 31,660,465
Notice both answers equal 31,660,465
With that explanation out of the way, let's continue. Next, we take the number 31,660,465 and divide it by 2:
31,660,465 ÷ 2 = 15,830,232.5
If the quotient is a whole number, then 2 and 15,830,232.5 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 | 31,660,465 | |
| -1 | -31,660,465 |
Now, we try dividing 31,660,465 by 3:
31,660,465 ÷ 3 = 10,553,488.3333
If the quotient is a whole number, then 3 and 10,553,488.3333 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 | 31,660,465 | |
| -1 | -31,660,465 |
Let's try dividing by 4:
31,660,465 ÷ 4 = 7,915,116.25
If the quotient is a whole number, then 4 and 7,915,116.25 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 | 31,660,465 | |
| -1 | 31,660,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 127 | 365 | 635 | 683 | 3,415 | 9,271 | 46,355 | 49,859 | 86,741 | 249,295 | 433,705 | 6,332,093 | 31,660,465 |
| -1 | -5 | -73 | -127 | -365 | -635 | -683 | -3,415 | -9,271 | -46,355 | -49,859 | -86,741 | -249,295 | -433,705 | -6,332,093 | -31,660,465 |
