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 2,547,325, 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 | 2,547,325 | |
| -1 | -2,547,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,547,325.
Example:
1 x 2,547,325 = 2,547,325
and
-1 x -2,547,325 = 2,547,325
Notice both answers equal 2,547,325
With that explanation out of the way, let's continue. Next, we take the number 2,547,325 and divide it by 2:
2,547,325 ÷ 2 = 1,273,662.5
If the quotient is a whole number, then 2 and 1,273,662.5 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 | 2,547,325 | |
| -1 | -2,547,325 |
Now, we try dividing 2,547,325 by 3:
2,547,325 ÷ 3 = 849,108.3333
If the quotient is a whole number, then 3 and 849,108.3333 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 | 2,547,325 | |
| -1 | -2,547,325 |
Let's try dividing by 4:
2,547,325 ÷ 4 = 636,831.25
If the quotient is a whole number, then 4 and 636,831.25 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 | 2,547,325 | |
| -1 | 2,547,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 59 | 157 | 275 | 295 | 649 | 785 | 1,475 | 1,727 | 3,245 | 3,925 | 8,635 | 9,263 | 16,225 | 43,175 | 46,315 | 101,893 | 231,575 | 509,465 | 2,547,325 |
| -1 | -5 | -11 | -25 | -55 | -59 | -157 | -275 | -295 | -649 | -785 | -1,475 | -1,727 | -3,245 | -3,925 | -8,635 | -9,263 | -16,225 | -43,175 | -46,315 | -101,893 | -231,575 | -509,465 | -2,547,325 |
