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 31,192,297, 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 | 31,192,297 | |
| -1 | -31,192,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,192,297.
Example:
1 x 31,192,297 = 31,192,297
and
-1 x -31,192,297 = 31,192,297
Notice both answers equal 31,192,297
With that explanation out of the way, let's continue. Next, we take the number 31,192,297 and divide it by 2:
31,192,297 ÷ 2 = 15,596,148.5
If the quotient is a whole number, then 2 and 15,596,148.5 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 | 31,192,297 | |
| -1 | -31,192,297 |
Now, we try dividing 31,192,297 by 3:
31,192,297 ÷ 3 = 10,397,432.3333
If the quotient is a whole number, then 3 and 10,397,432.3333 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 | 31,192,297 | |
| -1 | -31,192,297 |
Let's try dividing by 4:
31,192,297 ÷ 4 = 7,798,074.25
If the quotient is a whole number, then 4 and 7,798,074.25 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 | 31,192,297 | |
| -1 | 31,192,297 |
If you did it right, you will end up with this table:
| 1 | 17 | 59 | 137 | 227 | 1,003 | 2,329 | 3,859 | 8,083 | 13,393 | 31,099 | 137,411 | 227,681 | 528,683 | 1,834,841 | 31,192,297 |
| -1 | -17 | -59 | -137 | -227 | -1,003 | -2,329 | -3,859 | -8,083 | -13,393 | -31,099 | -137,411 | -227,681 | -528,683 | -1,834,841 | -31,192,297 |
