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 26,040,773, 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 | 26,040,773 | |
| -1 | -26,040,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,040,773.
Example:
1 x 26,040,773 = 26,040,773
and
-1 x -26,040,773 = 26,040,773
Notice both answers equal 26,040,773
With that explanation out of the way, let's continue. Next, we take the number 26,040,773 and divide it by 2:
26,040,773 ÷ 2 = 13,020,386.5
If the quotient is a whole number, then 2 and 13,020,386.5 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 | 26,040,773 | |
| -1 | -26,040,773 |
Now, we try dividing 26,040,773 by 3:
26,040,773 ÷ 3 = 8,680,257.6667
If the quotient is a whole number, then 3 and 8,680,257.6667 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 | 26,040,773 | |
| -1 | -26,040,773 |
Let's try dividing by 4:
26,040,773 ÷ 4 = 6,510,193.25
If the quotient is a whole number, then 4 and 6,510,193.25 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 | 26,040,773 | |
| -1 | 26,040,773 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 47 | 121 | 209 | 241 | 517 | 893 | 2,299 | 2,651 | 4,579 | 5,687 | 9,823 | 11,327 | 29,161 | 50,369 | 108,053 | 124,597 | 215,213 | 554,059 | 1,370,567 | 2,367,343 | 26,040,773 |
| -1 | -11 | -19 | -47 | -121 | -209 | -241 | -517 | -893 | -2,299 | -2,651 | -4,579 | -5,687 | -9,823 | -11,327 | -29,161 | -50,369 | -108,053 | -124,597 | -215,213 | -554,059 | -1,370,567 | -2,367,343 | -26,040,773 |
