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 25,567,711, 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 | 25,567,711 | |
| -1 | -25,567,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,567,711.
Example:
1 x 25,567,711 = 25,567,711
and
-1 x -25,567,711 = 25,567,711
Notice both answers equal 25,567,711
With that explanation out of the way, let's continue. Next, we take the number 25,567,711 and divide it by 2:
25,567,711 ÷ 2 = 12,783,855.5
If the quotient is a whole number, then 2 and 12,783,855.5 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 | 25,567,711 | |
| -1 | -25,567,711 |
Now, we try dividing 25,567,711 by 3:
25,567,711 ÷ 3 = 8,522,570.3333
If the quotient is a whole number, then 3 and 8,522,570.3333 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 | 25,567,711 | |
| -1 | -25,567,711 |
Let's try dividing by 4:
25,567,711 ÷ 4 = 6,391,927.75
If the quotient is a whole number, then 4 and 6,391,927.75 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 | 25,567,711 | |
| -1 | 25,567,711 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 19 | 221 | 247 | 323 | 4,199 | 6,089 | 79,157 | 103,513 | 115,691 | 1,345,669 | 1,503,983 | 1,966,747 | 25,567,711 |
| -1 | -13 | -17 | -19 | -221 | -247 | -323 | -4,199 | -6,089 | -79,157 | -103,513 | -115,691 | -1,345,669 | -1,503,983 | -1,966,747 | -25,567,711 |
