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 25,261,061, 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 | 25,261,061 | |
| -1 | -25,261,061 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,261,061.
Example:
1 x 25,261,061 = 25,261,061
and
-1 x -25,261,061 = 25,261,061
Notice both answers equal 25,261,061
With that explanation out of the way, let's continue. Next, we take the number 25,261,061 and divide it by 2:
25,261,061 ÷ 2 = 12,630,530.5
If the quotient is a whole number, then 2 and 12,630,530.5 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 | 25,261,061 | |
| -1 | -25,261,061 |
Now, we try dividing 25,261,061 by 3:
25,261,061 ÷ 3 = 8,420,353.6667
If the quotient is a whole number, then 3 and 8,420,353.6667 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 | 25,261,061 | |
| -1 | -25,261,061 |
Let's try dividing by 4:
25,261,061 ÷ 4 = 6,315,265.25
If the quotient is a whole number, then 4 and 6,315,265.25 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 | 25,261,061 | |
| -1 | 25,261,061 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 156,901 | 1,098,307 | 3,608,723 | 25,261,061 |
| -1 | -7 | -23 | -161 | -156,901 | -1,098,307 | -3,608,723 | -25,261,061 |
