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 25,314,605, 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 | 25,314,605 | |
| -1 | -25,314,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,314,605.
Example:
1 x 25,314,605 = 25,314,605
and
-1 x -25,314,605 = 25,314,605
Notice both answers equal 25,314,605
With that explanation out of the way, let's continue. Next, we take the number 25,314,605 and divide it by 2:
25,314,605 ÷ 2 = 12,657,302.5
If the quotient is a whole number, then 2 and 12,657,302.5 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 | 25,314,605 | |
| -1 | -25,314,605 |
Now, we try dividing 25,314,605 by 3:
25,314,605 ÷ 3 = 8,438,201.6667
If the quotient is a whole number, then 3 and 8,438,201.6667 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 | 25,314,605 | |
| -1 | -25,314,605 |
Let's try dividing by 4:
25,314,605 ÷ 4 = 6,328,651.25
If the quotient is a whole number, then 4 and 6,328,651.25 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 | 25,314,605 | |
| -1 | 25,314,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 251 | 877 | 1,255 | 4,385 | 5,773 | 20,171 | 28,865 | 100,855 | 220,127 | 1,100,635 | 5,062,921 | 25,314,605 |
| -1 | -5 | -23 | -115 | -251 | -877 | -1,255 | -4,385 | -5,773 | -20,171 | -28,865 | -100,855 | -220,127 | -1,100,635 | -5,062,921 | -25,314,605 |
