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 25,432,555, 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 | 25,432,555 | |
| -1 | -25,432,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,432,555.
Example:
1 x 25,432,555 = 25,432,555
and
-1 x -25,432,555 = 25,432,555
Notice both answers equal 25,432,555
With that explanation out of the way, let's continue. Next, we take the number 25,432,555 and divide it by 2:
25,432,555 ÷ 2 = 12,716,277.5
If the quotient is a whole number, then 2 and 12,716,277.5 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 | 25,432,555 | |
| -1 | -25,432,555 |
Now, we try dividing 25,432,555 by 3:
25,432,555 ÷ 3 = 8,477,518.3333
If the quotient is a whole number, then 3 and 8,477,518.3333 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 | 25,432,555 | |
| -1 | -25,432,555 |
Let's try dividing by 4:
25,432,555 ÷ 4 = 6,358,138.75
If the quotient is a whole number, then 4 and 6,358,138.75 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 | 25,432,555 | |
| -1 | 25,432,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 71 | 155 | 355 | 2,201 | 2,311 | 11,005 | 11,555 | 71,641 | 164,081 | 358,205 | 820,405 | 5,086,511 | 25,432,555 |
| -1 | -5 | -31 | -71 | -155 | -355 | -2,201 | -2,311 | -11,005 | -11,555 | -71,641 | -164,081 | -358,205 | -820,405 | -5,086,511 | -25,432,555 |
