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 31,227,025, 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 | 31,227,025 | |
| -1 | -31,227,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,227,025.
Example:
1 x 31,227,025 = 31,227,025
and
-1 x -31,227,025 = 31,227,025
Notice both answers equal 31,227,025
With that explanation out of the way, let's continue. Next, we take the number 31,227,025 and divide it by 2:
31,227,025 ÷ 2 = 15,613,512.5
If the quotient is a whole number, then 2 and 15,613,512.5 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 | 31,227,025 | |
| -1 | -31,227,025 |
Now, we try dividing 31,227,025 by 3:
31,227,025 ÷ 3 = 10,409,008.3333
If the quotient is a whole number, then 3 and 10,409,008.3333 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 | 31,227,025 | |
| -1 | -31,227,025 |
Let's try dividing by 4:
31,227,025 ÷ 4 = 7,806,756.25
If the quotient is a whole number, then 4 and 7,806,756.25 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 | 31,227,025 | |
| -1 | 31,227,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 67 | 103 | 181 | 335 | 515 | 905 | 1,675 | 2,575 | 4,525 | 6,901 | 12,127 | 18,643 | 34,505 | 60,635 | 93,215 | 172,525 | 303,175 | 466,075 | 1,249,081 | 6,245,405 | 31,227,025 |
| -1 | -5 | -25 | -67 | -103 | -181 | -335 | -515 | -905 | -1,675 | -2,575 | -4,525 | -6,901 | -12,127 | -18,643 | -34,505 | -60,635 | -93,215 | -172,525 | -303,175 | -466,075 | -1,249,081 | -6,245,405 | -31,227,025 |
