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 225,530,653, 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 | 225,530,653 | |
| -1 | -225,530,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,530,653.
Example:
1 x 225,530,653 = 225,530,653
and
-1 x -225,530,653 = 225,530,653
Notice both answers equal 225,530,653
With that explanation out of the way, let's continue. Next, we take the number 225,530,653 and divide it by 2:
225,530,653 ÷ 2 = 112,765,326.5
If the quotient is a whole number, then 2 and 112,765,326.5 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 | 225,530,653 | |
| -1 | -225,530,653 |
Now, we try dividing 225,530,653 by 3:
225,530,653 ÷ 3 = 75,176,884.3333
If the quotient is a whole number, then 3 and 75,176,884.3333 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 | 225,530,653 | |
| -1 | -225,530,653 |
Let's try dividing by 4:
225,530,653 ÷ 4 = 56,382,663.25
If the quotient is a whole number, then 4 and 56,382,663.25 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 | 225,530,653 | |
| -1 | 225,530,653 |
If you did it right, you will end up with this table:
| 1 | 17 | 73 | 263 | 691 | 1,241 | 4,471 | 11,747 | 19,199 | 50,443 | 181,733 | 326,383 | 857,531 | 3,089,461 | 13,266,509 | 225,530,653 |
| -1 | -17 | -73 | -263 | -691 | -1,241 | -4,471 | -11,747 | -19,199 | -50,443 | -181,733 | -326,383 | -857,531 | -3,089,461 | -13,266,509 | -225,530,653 |
