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 225,002,503, 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 | 225,002,503 | |
| -1 | -225,002,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,002,503.
Example:
1 x 225,002,503 = 225,002,503
and
-1 x -225,002,503 = 225,002,503
Notice both answers equal 225,002,503
With that explanation out of the way, let's continue. Next, we take the number 225,002,503 and divide it by 2:
225,002,503 ÷ 2 = 112,501,251.5
If the quotient is a whole number, then 2 and 112,501,251.5 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 | 225,002,503 | |
| -1 | -225,002,503 |
Now, we try dividing 225,002,503 by 3:
225,002,503 ÷ 3 = 75,000,834.3333
If the quotient is a whole number, then 3 and 75,000,834.3333 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 | 225,002,503 | |
| -1 | -225,002,503 |
Let's try dividing by 4:
225,002,503 ÷ 4 = 56,250,625.75
If the quotient is a whole number, then 4 and 56,250,625.75 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 | 225,002,503 | |
| -1 | 225,002,503 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 29 | 209 | 319 | 551 | 6,061 | 37,123 | 408,353 | 705,337 | 1,076,567 | 7,758,707 | 11,842,237 | 20,454,773 | 225,002,503 |
| -1 | -11 | -19 | -29 | -209 | -319 | -551 | -6,061 | -37,123 | -408,353 | -705,337 | -1,076,567 | -7,758,707 | -11,842,237 | -20,454,773 | -225,002,503 |
