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 31,227,007, 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 | 31,227,007 | |
| -1 | -31,227,007 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,227,007.
Example:
1 x 31,227,007 = 31,227,007
and
-1 x -31,227,007 = 31,227,007
Notice both answers equal 31,227,007
With that explanation out of the way, let's continue. Next, we take the number 31,227,007 and divide it by 2:
31,227,007 ÷ 2 = 15,613,503.5
If the quotient is a whole number, then 2 and 15,613,503.5 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 | 31,227,007 | |
| -1 | -31,227,007 |
Now, we try dividing 31,227,007 by 3:
31,227,007 ÷ 3 = 10,409,002.3333
If the quotient is a whole number, then 3 and 10,409,002.3333 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 | 31,227,007 | |
| -1 | -31,227,007 |
Let's try dividing by 4:
31,227,007 ÷ 4 = 7,806,751.75
If the quotient is a whole number, then 4 and 7,806,751.75 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 | 31,227,007 | |
| -1 | 31,227,007 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 83 | 497 | 581 | 757 | 5,299 | 5,893 | 41,251 | 53,747 | 62,831 | 376,229 | 439,817 | 4,461,001 | 31,227,007 |
| -1 | -7 | -71 | -83 | -497 | -581 | -757 | -5,299 | -5,893 | -41,251 | -53,747 | -62,831 | -376,229 | -439,817 | -4,461,001 | -31,227,007 |
