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 26,202,215, 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 | 26,202,215 | |
| -1 | -26,202,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,202,215.
Example:
1 x 26,202,215 = 26,202,215
and
-1 x -26,202,215 = 26,202,215
Notice both answers equal 26,202,215
With that explanation out of the way, let's continue. Next, we take the number 26,202,215 and divide it by 2:
26,202,215 ÷ 2 = 13,101,107.5
If the quotient is a whole number, then 2 and 13,101,107.5 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 | 26,202,215 | |
| -1 | -26,202,215 |
Now, we try dividing 26,202,215 by 3:
26,202,215 ÷ 3 = 8,734,071.6667
If the quotient is a whole number, then 3 and 8,734,071.6667 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 | 26,202,215 | |
| -1 | -26,202,215 |
Let's try dividing by 4:
26,202,215 ÷ 4 = 6,550,553.75
If the quotient is a whole number, then 4 and 6,550,553.75 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 | 26,202,215 | |
| -1 | 26,202,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 491 | 821 | 2,455 | 4,105 | 6,383 | 10,673 | 31,915 | 53,365 | 403,111 | 2,015,555 | 5,240,443 | 26,202,215 |
| -1 | -5 | -13 | -65 | -491 | -821 | -2,455 | -4,105 | -6,383 | -10,673 | -31,915 | -53,365 | -403,111 | -2,015,555 | -5,240,443 | -26,202,215 |
