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 13,738,625, 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 | 13,738,625 | |
| -1 | -13,738,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,738,625.
Example:
1 x 13,738,625 = 13,738,625
and
-1 x -13,738,625 = 13,738,625
Notice both answers equal 13,738,625
With that explanation out of the way, let's continue. Next, we take the number 13,738,625 and divide it by 2:
13,738,625 ÷ 2 = 6,869,312.5
If the quotient is a whole number, then 2 and 6,869,312.5 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 | 13,738,625 | |
| -1 | -13,738,625 |
Now, we try dividing 13,738,625 by 3:
13,738,625 ÷ 3 = 4,579,541.6667
If the quotient is a whole number, then 3 and 4,579,541.6667 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 | 13,738,625 | |
| -1 | -13,738,625 |
Let's try dividing by 4:
13,738,625 ÷ 4 = 3,434,656.25
If the quotient is a whole number, then 4 and 3,434,656.25 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 | 13,738,625 | |
| -1 | 13,738,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 131 | 655 | 839 | 3,275 | 4,195 | 16,375 | 20,975 | 104,875 | 109,909 | 549,545 | 2,747,725 | 13,738,625 |
| -1 | -5 | -25 | -125 | -131 | -655 | -839 | -3,275 | -4,195 | -16,375 | -20,975 | -104,875 | -109,909 | -549,545 | -2,747,725 | -13,738,625 |
