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 13,971,595, 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 | 13,971,595 | |
| -1 | -13,971,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,971,595.
Example:
1 x 13,971,595 = 13,971,595
and
-1 x -13,971,595 = 13,971,595
Notice both answers equal 13,971,595
With that explanation out of the way, let's continue. Next, we take the number 13,971,595 and divide it by 2:
13,971,595 ÷ 2 = 6,985,797.5
If the quotient is a whole number, then 2 and 6,985,797.5 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 | 13,971,595 | |
| -1 | -13,971,595 |
Now, we try dividing 13,971,595 by 3:
13,971,595 ÷ 3 = 4,657,198.3333
If the quotient is a whole number, then 3 and 4,657,198.3333 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 | 13,971,595 | |
| -1 | -13,971,595 |
Let's try dividing by 4:
13,971,595 ÷ 4 = 3,492,898.75
If the quotient is a whole number, then 4 and 3,492,898.75 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 | 13,971,595 | |
| -1 | 13,971,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 265 | 583 | 2,915 | 4,793 | 23,965 | 52,723 | 254,029 | 263,615 | 1,270,145 | 2,794,319 | 13,971,595 |
| -1 | -5 | -11 | -53 | -55 | -265 | -583 | -2,915 | -4,793 | -23,965 | -52,723 | -254,029 | -263,615 | -1,270,145 | -2,794,319 | -13,971,595 |
