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 26,015,341, 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 | 26,015,341 | |
| -1 | -26,015,341 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,015,341.
Example:
1 x 26,015,341 = 26,015,341
and
-1 x -26,015,341 = 26,015,341
Notice both answers equal 26,015,341
With that explanation out of the way, let's continue. Next, we take the number 26,015,341 and divide it by 2:
26,015,341 ÷ 2 = 13,007,670.5
If the quotient is a whole number, then 2 and 13,007,670.5 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 | 26,015,341 | |
| -1 | -26,015,341 |
Now, we try dividing 26,015,341 by 3:
26,015,341 ÷ 3 = 8,671,780.3333
If the quotient is a whole number, then 3 and 8,671,780.3333 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 | 26,015,341 | |
| -1 | -26,015,341 |
Let's try dividing by 4:
26,015,341 ÷ 4 = 6,503,835.25
If the quotient is a whole number, then 4 and 6,503,835.25 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 | 26,015,341 | |
| -1 | 26,015,341 |
If you did it right, you will end up with this table:
| 1 | 11 | 61 | 137 | 283 | 671 | 1,507 | 3,113 | 8,357 | 17,263 | 38,771 | 91,927 | 189,893 | 426,481 | 2,365,031 | 26,015,341 |
| -1 | -11 | -61 | -137 | -283 | -671 | -1,507 | -3,113 | -8,357 | -17,263 | -38,771 | -91,927 | -189,893 | -426,481 | -2,365,031 | -26,015,341 |
