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 31,348,603, 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 | 31,348,603 | |
| -1 | -31,348,603 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,348,603.
Example:
1 x 31,348,603 = 31,348,603
and
-1 x -31,348,603 = 31,348,603
Notice both answers equal 31,348,603
With that explanation out of the way, let's continue. Next, we take the number 31,348,603 and divide it by 2:
31,348,603 ÷ 2 = 15,674,301.5
If the quotient is a whole number, then 2 and 15,674,301.5 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 | 31,348,603 | |
| -1 | -31,348,603 |
Now, we try dividing 31,348,603 by 3:
31,348,603 ÷ 3 = 10,449,534.3333
If the quotient is a whole number, then 3 and 10,449,534.3333 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 | 31,348,603 | |
| -1 | -31,348,603 |
Let's try dividing by 4:
31,348,603 ÷ 4 = 7,837,150.75
If the quotient is a whole number, then 4 and 7,837,150.75 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 | 31,348,603 | |
| -1 | 31,348,603 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 257 | 853 | 2,827 | 3,341 | 9,383 | 11,089 | 36,751 | 121,979 | 219,221 | 2,411,431 | 2,849,873 | 31,348,603 |
| -1 | -11 | -13 | -143 | -257 | -853 | -2,827 | -3,341 | -9,383 | -11,089 | -36,751 | -121,979 | -219,221 | -2,411,431 | -2,849,873 | -31,348,603 |
