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 31,453,535, 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 | 31,453,535 | |
| -1 | -31,453,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,453,535.
Example:
1 x 31,453,535 = 31,453,535
and
-1 x -31,453,535 = 31,453,535
Notice both answers equal 31,453,535
With that explanation out of the way, let's continue. Next, we take the number 31,453,535 and divide it by 2:
31,453,535 ÷ 2 = 15,726,767.5
If the quotient is a whole number, then 2 and 15,726,767.5 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 | 31,453,535 | |
| -1 | -31,453,535 |
Now, we try dividing 31,453,535 by 3:
31,453,535 ÷ 3 = 10,484,511.6667
If the quotient is a whole number, then 3 and 10,484,511.6667 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 | 31,453,535 | |
| -1 | -31,453,535 |
Let's try dividing by 4:
31,453,535 ÷ 4 = 7,863,383.75
If the quotient is a whole number, then 4 and 7,863,383.75 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 | 31,453,535 | |
| -1 | 31,453,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 479 | 571 | 2,395 | 2,855 | 11,017 | 13,133 | 55,085 | 65,665 | 273,509 | 1,367,545 | 6,290,707 | 31,453,535 |
| -1 | -5 | -23 | -115 | -479 | -571 | -2,395 | -2,855 | -11,017 | -13,133 | -55,085 | -65,665 | -273,509 | -1,367,545 | -6,290,707 | -31,453,535 |
