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 3,066,545, 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 | 3,066,545 | |
| -1 | -3,066,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,066,545.
Example:
1 x 3,066,545 = 3,066,545
and
-1 x -3,066,545 = 3,066,545
Notice both answers equal 3,066,545
With that explanation out of the way, let's continue. Next, we take the number 3,066,545 and divide it by 2:
3,066,545 ÷ 2 = 1,533,272.5
If the quotient is a whole number, then 2 and 1,533,272.5 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 | 3,066,545 | |
| -1 | -3,066,545 |
Now, we try dividing 3,066,545 by 3:
3,066,545 ÷ 3 = 1,022,181.6667
If the quotient is a whole number, then 3 and 1,022,181.6667 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 | 3,066,545 | |
| -1 | -3,066,545 |
Let's try dividing by 4:
3,066,545 ÷ 4 = 766,636.25
If the quotient is a whole number, then 4 and 766,636.25 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 | 3,066,545 | |
| -1 | 3,066,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 215 | 731 | 839 | 3,655 | 4,195 | 14,263 | 36,077 | 71,315 | 180,385 | 613,309 | 3,066,545 |
| -1 | -5 | -17 | -43 | -85 | -215 | -731 | -839 | -3,655 | -4,195 | -14,263 | -36,077 | -71,315 | -180,385 | -613,309 | -3,066,545 |
