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 636,025, 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 | 636,025 | |
| -1 | -636,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 636,025.
Example:
1 x 636,025 = 636,025
and
-1 x -636,025 = 636,025
Notice both answers equal 636,025
With that explanation out of the way, let's continue. Next, we take the number 636,025 and divide it by 2:
636,025 ÷ 2 = 318,012.5
If the quotient is a whole number, then 2 and 318,012.5 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 | 636,025 | |
| -1 | -636,025 |
Now, we try dividing 636,025 by 3:
636,025 ÷ 3 = 212,008.3333
If the quotient is a whole number, then 3 and 212,008.3333 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 | 636,025 | |
| -1 | -636,025 |
Let's try dividing by 4:
636,025 ÷ 4 = 159,006.25
If the quotient is a whole number, then 4 and 159,006.25 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 | 636,025 | |
| -1 | 636,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 25 | 65 | 95 | 103 | 247 | 325 | 475 | 515 | 1,235 | 1,339 | 1,957 | 2,575 | 6,175 | 6,695 | 9,785 | 25,441 | 33,475 | 48,925 | 127,205 | 636,025 |
| -1 | -5 | -13 | -19 | -25 | -65 | -95 | -103 | -247 | -325 | -475 | -515 | -1,235 | -1,339 | -1,957 | -2,575 | -6,175 | -6,695 | -9,785 | -25,441 | -33,475 | -48,925 | -127,205 | -636,025 |
