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 26,302,685, 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 | 26,302,685 | |
| -1 | -26,302,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,302,685.
Example:
1 x 26,302,685 = 26,302,685
and
-1 x -26,302,685 = 26,302,685
Notice both answers equal 26,302,685
With that explanation out of the way, let's continue. Next, we take the number 26,302,685 and divide it by 2:
26,302,685 ÷ 2 = 13,151,342.5
If the quotient is a whole number, then 2 and 13,151,342.5 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 | 26,302,685 | |
| -1 | -26,302,685 |
Now, we try dividing 26,302,685 by 3:
26,302,685 ÷ 3 = 8,767,561.6667
If the quotient is a whole number, then 3 and 8,767,561.6667 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 | 26,302,685 | |
| -1 | -26,302,685 |
Let's try dividing by 4:
26,302,685 ÷ 4 = 6,575,671.25
If the quotient is a whole number, then 4 and 6,575,671.25 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 | 26,302,685 | |
| -1 | 26,302,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 439 | 521 | 2,195 | 2,605 | 10,097 | 11,983 | 50,485 | 59,915 | 228,719 | 1,143,595 | 5,260,537 | 26,302,685 |
| -1 | -5 | -23 | -115 | -439 | -521 | -2,195 | -2,605 | -10,097 | -11,983 | -50,485 | -59,915 | -228,719 | -1,143,595 | -5,260,537 | -26,302,685 |
