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 13,969,793, 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 | 13,969,793 | |
| -1 | -13,969,793 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,969,793.
Example:
1 x 13,969,793 = 13,969,793
and
-1 x -13,969,793 = 13,969,793
Notice both answers equal 13,969,793
With that explanation out of the way, let's continue. Next, we take the number 13,969,793 and divide it by 2:
13,969,793 ÷ 2 = 6,984,896.5
If the quotient is a whole number, then 2 and 6,984,896.5 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 | 13,969,793 | |
| -1 | -13,969,793 |
Now, we try dividing 13,969,793 by 3:
13,969,793 ÷ 3 = 4,656,597.6667
If the quotient is a whole number, then 3 and 4,656,597.6667 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 | 13,969,793 | |
| -1 | -13,969,793 |
Let's try dividing by 4:
13,969,793 ÷ 4 = 3,492,448.25
If the quotient is a whole number, then 4 and 3,492,448.25 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 | 13,969,793 | |
| -1 | 13,969,793 |
If you did it right, you will end up with this table:
| 1 | 29 | 53 | 61 | 149 | 1,537 | 1,769 | 3,233 | 4,321 | 7,897 | 9,089 | 93,757 | 229,013 | 263,581 | 481,717 | 13,969,793 |
| -1 | -29 | -53 | -61 | -149 | -1,537 | -1,769 | -3,233 | -4,321 | -7,897 | -9,089 | -93,757 | -229,013 | -263,581 | -481,717 | -13,969,793 |
