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 204,001,525, 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 | 204,001,525 | |
| -1 | -204,001,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,001,525.
Example:
1 x 204,001,525 = 204,001,525
and
-1 x -204,001,525 = 204,001,525
Notice both answers equal 204,001,525
With that explanation out of the way, let's continue. Next, we take the number 204,001,525 and divide it by 2:
204,001,525 ÷ 2 = 102,000,762.5
If the quotient is a whole number, then 2 and 102,000,762.5 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 | 204,001,525 | |
| -1 | -204,001,525 |
Now, we try dividing 204,001,525 by 3:
204,001,525 ÷ 3 = 68,000,508.3333
If the quotient is a whole number, then 3 and 68,000,508.3333 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 | 204,001,525 | |
| -1 | -204,001,525 |
Let's try dividing by 4:
204,001,525 ÷ 4 = 51,000,381.25
If the quotient is a whole number, then 4 and 51,000,381.25 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 | 204,001,525 | |
| -1 | 204,001,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 325 | 455 | 2,275 | 89,671 | 448,355 | 627,697 | 1,165,723 | 2,241,775 | 3,138,485 | 5,828,615 | 8,160,061 | 15,692,425 | 29,143,075 | 40,800,305 | 204,001,525 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -325 | -455 | -2,275 | -89,671 | -448,355 | -627,697 | -1,165,723 | -2,241,775 | -3,138,485 | -5,828,615 | -8,160,061 | -15,692,425 | -29,143,075 | -40,800,305 | -204,001,525 |
