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 2,507,365, 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 | 2,507,365 | |
| -1 | -2,507,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,507,365.
Example:
1 x 2,507,365 = 2,507,365
and
-1 x -2,507,365 = 2,507,365
Notice both answers equal 2,507,365
With that explanation out of the way, let's continue. Next, we take the number 2,507,365 and divide it by 2:
2,507,365 ÷ 2 = 1,253,682.5
If the quotient is a whole number, then 2 and 1,253,682.5 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 | 2,507,365 | |
| -1 | -2,507,365 |
Now, we try dividing 2,507,365 by 3:
2,507,365 ÷ 3 = 835,788.3333
If the quotient is a whole number, then 3 and 835,788.3333 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 | 2,507,365 | |
| -1 | -2,507,365 |
Let's try dividing by 4:
2,507,365 ÷ 4 = 626,841.25
If the quotient is a whole number, then 4 and 626,841.25 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 | 2,507,365 | |
| -1 | 2,507,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 1,009 | 2,485 | 5,045 | 7,063 | 35,315 | 71,639 | 358,195 | 501,473 | 2,507,365 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -1,009 | -2,485 | -5,045 | -7,063 | -35,315 | -71,639 | -358,195 | -501,473 | -2,507,365 |
