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 13,710,739, 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 | 13,710,739 | |
| -1 | -13,710,739 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,710,739.
Example:
1 x 13,710,739 = 13,710,739
and
-1 x -13,710,739 = 13,710,739
Notice both answers equal 13,710,739
With that explanation out of the way, let's continue. Next, we take the number 13,710,739 and divide it by 2:
13,710,739 ÷ 2 = 6,855,369.5
If the quotient is a whole number, then 2 and 6,855,369.5 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 | 13,710,739 | |
| -1 | -13,710,739 |
Now, we try dividing 13,710,739 by 3:
13,710,739 ÷ 3 = 4,570,246.3333
If the quotient is a whole number, then 3 and 4,570,246.3333 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 | 13,710,739 | |
| -1 | -13,710,739 |
Let's try dividing by 4:
13,710,739 ÷ 4 = 3,427,684.75
If the quotient is a whole number, then 4 and 3,427,684.75 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 | 13,710,739 | |
| -1 | 13,710,739 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 71 | 343 | 497 | 563 | 3,479 | 3,941 | 24,353 | 27,587 | 39,973 | 193,109 | 279,811 | 1,958,677 | 13,710,739 |
| -1 | -7 | -49 | -71 | -343 | -497 | -563 | -3,479 | -3,941 | -24,353 | -27,587 | -39,973 | -193,109 | -279,811 | -1,958,677 | -13,710,739 |
