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 7,525,265, 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 | 7,525,265 | |
| -1 | -7,525,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,525,265.
Example:
1 x 7,525,265 = 7,525,265
and
-1 x -7,525,265 = 7,525,265
Notice both answers equal 7,525,265
With that explanation out of the way, let's continue. Next, we take the number 7,525,265 and divide it by 2:
7,525,265 ÷ 2 = 3,762,632.5
If the quotient is a whole number, then 2 and 3,762,632.5 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 | 7,525,265 | |
| -1 | -7,525,265 |
Now, we try dividing 7,525,265 by 3:
7,525,265 ÷ 3 = 2,508,421.6667
If the quotient is a whole number, then 3 and 2,508,421.6667 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 | 7,525,265 | |
| -1 | -7,525,265 |
Let's try dividing by 4:
7,525,265 ÷ 4 = 1,881,316.25
If the quotient is a whole number, then 4 and 1,881,316.25 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 | 7,525,265 | |
| -1 | 7,525,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 305 | 671 | 2,243 | 3,355 | 11,215 | 24,673 | 123,365 | 136,823 | 684,115 | 1,505,053 | 7,525,265 |
| -1 | -5 | -11 | -55 | -61 | -305 | -671 | -2,243 | -3,355 | -11,215 | -24,673 | -123,365 | -136,823 | -684,115 | -1,505,053 | -7,525,265 |
