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 263,367,185, 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 | 263,367,185 | |
| -1 | -263,367,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 263,367,185.
Example:
1 x 263,367,185 = 263,367,185
and
-1 x -263,367,185 = 263,367,185
Notice both answers equal 263,367,185
With that explanation out of the way, let's continue. Next, we take the number 263,367,185 and divide it by 2:
263,367,185 ÷ 2 = 131,683,592.5
If the quotient is a whole number, then 2 and 131,683,592.5 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 | 263,367,185 | |
| -1 | -263,367,185 |
Now, we try dividing 263,367,185 by 3:
263,367,185 ÷ 3 = 87,789,061.6667
If the quotient is a whole number, then 3 and 87,789,061.6667 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 | 263,367,185 | |
| -1 | -263,367,185 |
Let's try dividing by 4:
263,367,185 ÷ 4 = 65,841,796.25
If the quotient is a whole number, then 4 and 65,841,796.25 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 | 263,367,185 | |
| -1 | 263,367,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 149 | 337 | 745 | 1,049 | 1,685 | 5,245 | 50,213 | 156,301 | 251,065 | 353,513 | 781,505 | 1,767,565 | 52,673,437 | 263,367,185 |
| -1 | -5 | -149 | -337 | -745 | -1,049 | -1,685 | -5,245 | -50,213 | -156,301 | -251,065 | -353,513 | -781,505 | -1,767,565 | -52,673,437 | -263,367,185 |
