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 263,117,203, 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 | 263,117,203 | |
| -1 | -263,117,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 263,117,203.
Example:
1 x 263,117,203 = 263,117,203
and
-1 x -263,117,203 = 263,117,203
Notice both answers equal 263,117,203
With that explanation out of the way, let's continue. Next, we take the number 263,117,203 and divide it by 2:
263,117,203 ÷ 2 = 131,558,601.5
If the quotient is a whole number, then 2 and 131,558,601.5 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 | 263,117,203 | |
| -1 | -263,117,203 |
Now, we try dividing 263,117,203 by 3:
263,117,203 ÷ 3 = 87,705,734.3333
If the quotient is a whole number, then 3 and 87,705,734.3333 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 | 263,117,203 | |
| -1 | -263,117,203 |
Let's try dividing by 4:
263,117,203 ÷ 4 = 65,779,300.75
If the quotient is a whole number, then 4 and 65,779,300.75 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 | 263,117,203 | |
| -1 | 263,117,203 |
If you did it right, you will end up with this table:
| 1 | 29 | 127 | 199 | 359 | 3,683 | 5,771 | 10,411 | 25,273 | 45,593 | 71,441 | 732,917 | 1,322,197 | 2,071,789 | 9,073,007 | 263,117,203 |
| -1 | -29 | -127 | -199 | -359 | -3,683 | -5,771 | -10,411 | -25,273 | -45,593 | -71,441 | -732,917 | -1,322,197 | -2,071,789 | -9,073,007 | -263,117,203 |
