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 31,446,653, 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 | 31,446,653 | |
| -1 | -31,446,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,446,653.
Example:
1 x 31,446,653 = 31,446,653
and
-1 x -31,446,653 = 31,446,653
Notice both answers equal 31,446,653
With that explanation out of the way, let's continue. Next, we take the number 31,446,653 and divide it by 2:
31,446,653 ÷ 2 = 15,723,326.5
If the quotient is a whole number, then 2 and 15,723,326.5 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 | 31,446,653 | |
| -1 | -31,446,653 |
Now, we try dividing 31,446,653 by 3:
31,446,653 ÷ 3 = 10,482,217.6667
If the quotient is a whole number, then 3 and 10,482,217.6667 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 | 31,446,653 | |
| -1 | -31,446,653 |
Let's try dividing by 4:
31,446,653 ÷ 4 = 7,861,663.25
If the quotient is a whole number, then 4 and 7,861,663.25 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 | 31,446,653 | |
| -1 | 31,446,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 101 | 133 | 707 | 1,919 | 2,341 | 13,433 | 16,387 | 44,479 | 236,441 | 311,353 | 1,655,087 | 4,492,379 | 31,446,653 |
| -1 | -7 | -19 | -101 | -133 | -707 | -1,919 | -2,341 | -13,433 | -16,387 | -44,479 | -236,441 | -311,353 | -1,655,087 | -4,492,379 | -31,446,653 |
