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 26,513,245, 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 | 26,513,245 | |
| -1 | -26,513,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,513,245.
Example:
1 x 26,513,245 = 26,513,245
and
-1 x -26,513,245 = 26,513,245
Notice both answers equal 26,513,245
With that explanation out of the way, let's continue. Next, we take the number 26,513,245 and divide it by 2:
26,513,245 ÷ 2 = 13,256,622.5
If the quotient is a whole number, then 2 and 13,256,622.5 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 | 26,513,245 | |
| -1 | -26,513,245 |
Now, we try dividing 26,513,245 by 3:
26,513,245 ÷ 3 = 8,837,748.3333
If the quotient is a whole number, then 3 and 8,837,748.3333 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 | 26,513,245 | |
| -1 | -26,513,245 |
Let's try dividing by 4:
26,513,245 ÷ 4 = 6,628,311.25
If the quotient is a whole number, then 4 and 6,628,311.25 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 | 26,513,245 | |
| -1 | 26,513,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 197 | 985 | 2,167 | 2,447 | 10,835 | 12,235 | 26,917 | 134,585 | 482,059 | 2,410,295 | 5,302,649 | 26,513,245 |
| -1 | -5 | -11 | -55 | -197 | -985 | -2,167 | -2,447 | -10,835 | -12,235 | -26,917 | -134,585 | -482,059 | -2,410,295 | -5,302,649 | -26,513,245 |
