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 25,707,169, 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 | 25,707,169 | |
| -1 | -25,707,169 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,707,169.
Example:
1 x 25,707,169 = 25,707,169
and
-1 x -25,707,169 = 25,707,169
Notice both answers equal 25,707,169
With that explanation out of the way, let's continue. Next, we take the number 25,707,169 and divide it by 2:
25,707,169 ÷ 2 = 12,853,584.5
If the quotient is a whole number, then 2 and 12,853,584.5 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 | 25,707,169 | |
| -1 | -25,707,169 |
Now, we try dividing 25,707,169 by 3:
25,707,169 ÷ 3 = 8,569,056.3333
If the quotient is a whole number, then 3 and 8,569,056.3333 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 | 25,707,169 | |
| -1 | -25,707,169 |
Let's try dividing by 4:
25,707,169 ÷ 4 = 6,426,792.25
If the quotient is a whole number, then 4 and 6,426,792.25 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 | 25,707,169 | |
| -1 | 25,707,169 |
If you did it right, you will end up with this table:
| 1 | 23 | 61 | 73 | 251 | 1,403 | 1,679 | 4,453 | 5,773 | 15,311 | 18,323 | 102,419 | 352,153 | 421,429 | 1,117,703 | 25,707,169 |
| -1 | -23 | -61 | -73 | -251 | -1,403 | -1,679 | -4,453 | -5,773 | -15,311 | -18,323 | -102,419 | -352,153 | -421,429 | -1,117,703 | -25,707,169 |
