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 225,252,145, 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 | 225,252,145 | |
| -1 | -225,252,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,252,145.
Example:
1 x 225,252,145 = 225,252,145
and
-1 x -225,252,145 = 225,252,145
Notice both answers equal 225,252,145
With that explanation out of the way, let's continue. Next, we take the number 225,252,145 and divide it by 2:
225,252,145 ÷ 2 = 112,626,072.5
If the quotient is a whole number, then 2 and 112,626,072.5 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 | 225,252,145 | |
| -1 | -225,252,145 |
Now, we try dividing 225,252,145 by 3:
225,252,145 ÷ 3 = 75,084,048.3333
If the quotient is a whole number, then 3 and 75,084,048.3333 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 | 225,252,145 | |
| -1 | -225,252,145 |
Let's try dividing by 4:
225,252,145 ÷ 4 = 56,313,036.25
If the quotient is a whole number, then 4 and 56,313,036.25 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 | 225,252,145 | |
| -1 | 225,252,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 163 | 479 | 577 | 815 | 2,395 | 2,885 | 78,077 | 94,051 | 276,383 | 390,385 | 470,255 | 1,381,915 | 45,050,429 | 225,252,145 |
| -1 | -5 | -163 | -479 | -577 | -815 | -2,395 | -2,885 | -78,077 | -94,051 | -276,383 | -390,385 | -470,255 | -1,381,915 | -45,050,429 | -225,252,145 |
