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 13,773,859, 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 | 13,773,859 | |
| -1 | -13,773,859 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,773,859.
Example:
1 x 13,773,859 = 13,773,859
and
-1 x -13,773,859 = 13,773,859
Notice both answers equal 13,773,859
With that explanation out of the way, let's continue. Next, we take the number 13,773,859 and divide it by 2:
13,773,859 ÷ 2 = 6,886,929.5
If the quotient is a whole number, then 2 and 6,886,929.5 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 | 13,773,859 | |
| -1 | -13,773,859 |
Now, we try dividing 13,773,859 by 3:
13,773,859 ÷ 3 = 4,591,286.3333
If the quotient is a whole number, then 3 and 4,591,286.3333 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 | 13,773,859 | |
| -1 | -13,773,859 |
Let's try dividing by 4:
13,773,859 ÷ 4 = 3,443,464.75
If the quotient is a whole number, then 4 and 3,443,464.75 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 | 13,773,859 | |
| -1 | 13,773,859 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 73 | 187 | 803 | 1,009 | 1,241 | 11,099 | 13,651 | 17,153 | 73,657 | 188,683 | 810,227 | 1,252,169 | 13,773,859 |
| -1 | -11 | -17 | -73 | -187 | -803 | -1,009 | -1,241 | -11,099 | -13,651 | -17,153 | -73,657 | -188,683 | -810,227 | -1,252,169 | -13,773,859 |
