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 2,496,725, 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 | 2,496,725 | |
| -1 | -2,496,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,496,725.
Example:
1 x 2,496,725 = 2,496,725
and
-1 x -2,496,725 = 2,496,725
Notice both answers equal 2,496,725
With that explanation out of the way, let's continue. Next, we take the number 2,496,725 and divide it by 2:
2,496,725 ÷ 2 = 1,248,362.5
If the quotient is a whole number, then 2 and 1,248,362.5 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 | 2,496,725 | |
| -1 | -2,496,725 |
Now, we try dividing 2,496,725 by 3:
2,496,725 ÷ 3 = 832,241.6667
If the quotient is a whole number, then 3 and 832,241.6667 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 | 2,496,725 | |
| -1 | -2,496,725 |
Let's try dividing by 4:
2,496,725 ÷ 4 = 624,181.25
If the quotient is a whole number, then 4 and 624,181.25 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 | 2,496,725 | |
| -1 | 2,496,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,297 | 1,925 | 6,485 | 9,079 | 14,267 | 32,425 | 45,395 | 71,335 | 99,869 | 226,975 | 356,675 | 499,345 | 2,496,725 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,297 | -1,925 | -6,485 | -9,079 | -14,267 | -32,425 | -45,395 | -71,335 | -99,869 | -226,975 | -356,675 | -499,345 | -2,496,725 |
