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 13,969,747, 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 | 13,969,747 | |
| -1 | -13,969,747 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,969,747.
Example:
1 x 13,969,747 = 13,969,747
and
-1 x -13,969,747 = 13,969,747
Notice both answers equal 13,969,747
With that explanation out of the way, let's continue. Next, we take the number 13,969,747 and divide it by 2:
13,969,747 ÷ 2 = 6,984,873.5
If the quotient is a whole number, then 2 and 6,984,873.5 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 | 13,969,747 | |
| -1 | -13,969,747 |
Now, we try dividing 13,969,747 by 3:
13,969,747 ÷ 3 = 4,656,582.3333
If the quotient is a whole number, then 3 and 4,656,582.3333 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 | 13,969,747 | |
| -1 | -13,969,747 |
Let's try dividing by 4:
13,969,747 ÷ 4 = 3,492,436.75
If the quotient is a whole number, then 4 and 3,492,436.75 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 | 13,969,747 | |
| -1 | 13,969,747 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 71 | 341 | 577 | 781 | 2,201 | 6,347 | 17,887 | 24,211 | 40,967 | 196,757 | 450,637 | 1,269,977 | 13,969,747 |
| -1 | -11 | -31 | -71 | -341 | -577 | -781 | -2,201 | -6,347 | -17,887 | -24,211 | -40,967 | -196,757 | -450,637 | -1,269,977 | -13,969,747 |
