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 2,536,025, 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 | 2,536,025 | |
| -1 | -2,536,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,536,025.
Example:
1 x 2,536,025 = 2,536,025
and
-1 x -2,536,025 = 2,536,025
Notice both answers equal 2,536,025
With that explanation out of the way, let's continue. Next, we take the number 2,536,025 and divide it by 2:
2,536,025 ÷ 2 = 1,268,012.5
If the quotient is a whole number, then 2 and 1,268,012.5 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 | 2,536,025 | |
| -1 | -2,536,025 |
Now, we try dividing 2,536,025 by 3:
2,536,025 ÷ 3 = 845,341.6667
If the quotient is a whole number, then 3 and 845,341.6667 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 | 2,536,025 | |
| -1 | -2,536,025 |
Let's try dividing by 4:
2,536,025 ÷ 4 = 634,006.25
If the quotient is a whole number, then 4 and 634,006.25 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 | 2,536,025 | |
| -1 | 2,536,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 281 | 361 | 475 | 1,405 | 1,805 | 5,339 | 7,025 | 9,025 | 26,695 | 101,441 | 133,475 | 507,205 | 2,536,025 |
| -1 | -5 | -19 | -25 | -95 | -281 | -361 | -475 | -1,405 | -1,805 | -5,339 | -7,025 | -9,025 | -26,695 | -101,441 | -133,475 | -507,205 | -2,536,025 |
