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 25,290,295, 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 | 25,290,295 | |
| -1 | -25,290,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,290,295.
Example:
1 x 25,290,295 = 25,290,295
and
-1 x -25,290,295 = 25,290,295
Notice both answers equal 25,290,295
With that explanation out of the way, let's continue. Next, we take the number 25,290,295 and divide it by 2:
25,290,295 ÷ 2 = 12,645,147.5
If the quotient is a whole number, then 2 and 12,645,147.5 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 | 25,290,295 | |
| -1 | -25,290,295 |
Now, we try dividing 25,290,295 by 3:
25,290,295 ÷ 3 = 8,430,098.3333
If the quotient is a whole number, then 3 and 8,430,098.3333 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 | 25,290,295 | |
| -1 | -25,290,295 |
Let's try dividing by 4:
25,290,295 ÷ 4 = 6,322,573.75
If the quotient is a whole number, then 4 and 6,322,573.75 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 | 25,290,295 | |
| -1 | 25,290,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 283 | 293 | 305 | 1,415 | 1,465 | 17,263 | 17,873 | 82,919 | 86,315 | 89,365 | 414,595 | 5,058,059 | 25,290,295 |
| -1 | -5 | -61 | -283 | -293 | -305 | -1,415 | -1,465 | -17,263 | -17,873 | -82,919 | -86,315 | -89,365 | -414,595 | -5,058,059 | -25,290,295 |
