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 225,020,159, 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 | 225,020,159 | |
| -1 | -225,020,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,020,159.
Example:
1 x 225,020,159 = 225,020,159
and
-1 x -225,020,159 = 225,020,159
Notice both answers equal 225,020,159
With that explanation out of the way, let's continue. Next, we take the number 225,020,159 and divide it by 2:
225,020,159 ÷ 2 = 112,510,079.5
If the quotient is a whole number, then 2 and 112,510,079.5 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 | 225,020,159 | |
| -1 | -225,020,159 |
Now, we try dividing 225,020,159 by 3:
225,020,159 ÷ 3 = 75,006,719.6667
If the quotient is a whole number, then 3 and 75,006,719.6667 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 | 225,020,159 | |
| -1 | -225,020,159 |
Let's try dividing by 4:
225,020,159 ÷ 4 = 56,255,039.75
If the quotient is a whole number, then 4 and 56,255,039.75 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 | 225,020,159 | |
| -1 | 225,020,159 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 59 | 91 | 413 | 767 | 5,369 | 41,911 | 293,377 | 544,843 | 2,472,749 | 3,813,901 | 17,309,243 | 32,145,737 | 225,020,159 |
| -1 | -7 | -13 | -59 | -91 | -413 | -767 | -5,369 | -41,911 | -293,377 | -544,843 | -2,472,749 | -3,813,901 | -17,309,243 | -32,145,737 | -225,020,159 |
