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 31,677,547, 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 | 31,677,547 | |
| -1 | -31,677,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,677,547.
Example:
1 x 31,677,547 = 31,677,547
and
-1 x -31,677,547 = 31,677,547
Notice both answers equal 31,677,547
With that explanation out of the way, let's continue. Next, we take the number 31,677,547 and divide it by 2:
31,677,547 ÷ 2 = 15,838,773.5
If the quotient is a whole number, then 2 and 15,838,773.5 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 | 31,677,547 | |
| -1 | -31,677,547 |
Now, we try dividing 31,677,547 by 3:
31,677,547 ÷ 3 = 10,559,182.3333
If the quotient is a whole number, then 3 and 10,559,182.3333 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 | 31,677,547 | |
| -1 | -31,677,547 |
Let's try dividing by 4:
31,677,547 ÷ 4 = 7,919,386.75
If the quotient is a whole number, then 4 and 7,919,386.75 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 | 31,677,547 | |
| -1 | 31,677,547 |
If you did it right, you will end up with this table:
| 1 | 11 | 73 | 103 | 383 | 803 | 1,133 | 4,213 | 7,519 | 27,959 | 39,449 | 82,709 | 307,549 | 433,939 | 2,879,777 | 31,677,547 |
| -1 | -11 | -73 | -103 | -383 | -803 | -1,133 | -4,213 | -7,519 | -27,959 | -39,449 | -82,709 | -307,549 | -433,939 | -2,879,777 | -31,677,547 |
