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 3,165,547, 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 | 3,165,547 | |
| -1 | -3,165,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,165,547.
Example:
1 x 3,165,547 = 3,165,547
and
-1 x -3,165,547 = 3,165,547
Notice both answers equal 3,165,547
With that explanation out of the way, let's continue. Next, we take the number 3,165,547 and divide it by 2:
3,165,547 ÷ 2 = 1,582,773.5
If the quotient is a whole number, then 2 and 1,582,773.5 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 | 3,165,547 | |
| -1 | -3,165,547 |
Now, we try dividing 3,165,547 by 3:
3,165,547 ÷ 3 = 1,055,182.3333
If the quotient is a whole number, then 3 and 1,055,182.3333 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 | 3,165,547 | |
| -1 | -3,165,547 |
Let's try dividing by 4:
3,165,547 ÷ 4 = 791,386.75
If the quotient is a whole number, then 4 and 791,386.75 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 | 3,165,547 | |
| -1 | 3,165,547 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 343 | 539 | 839 | 3,773 | 5,873 | 9,229 | 41,111 | 64,603 | 287,777 | 452,221 | 3,165,547 |
| -1 | -7 | -11 | -49 | -77 | -343 | -539 | -839 | -3,773 | -5,873 | -9,229 | -41,111 | -64,603 | -287,777 | -452,221 | -3,165,547 |
