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 25,033,169, 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 | 25,033,169 | |
| -1 | -25,033,169 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,033,169.
Example:
1 x 25,033,169 = 25,033,169
and
-1 x -25,033,169 = 25,033,169
Notice both answers equal 25,033,169
With that explanation out of the way, let's continue. Next, we take the number 25,033,169 and divide it by 2:
25,033,169 ÷ 2 = 12,516,584.5
If the quotient is a whole number, then 2 and 12,516,584.5 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 | 25,033,169 | |
| -1 | -25,033,169 |
Now, we try dividing 25,033,169 by 3:
25,033,169 ÷ 3 = 8,344,389.6667
If the quotient is a whole number, then 3 and 8,344,389.6667 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 | 25,033,169 | |
| -1 | -25,033,169 |
Let's try dividing by 4:
25,033,169 ÷ 4 = 6,258,292.25
If the quotient is a whole number, then 4 and 6,258,292.25 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 | 25,033,169 | |
| -1 | 25,033,169 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 59 | 343 | 413 | 1,237 | 2,891 | 8,659 | 20,237 | 60,613 | 72,983 | 424,291 | 510,881 | 3,576,167 | 25,033,169 |
| -1 | -7 | -49 | -59 | -343 | -413 | -1,237 | -2,891 | -8,659 | -20,237 | -60,613 | -72,983 | -424,291 | -510,881 | -3,576,167 | -25,033,169 |
