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 2,006,165, 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 | 2,006,165 | |
| -1 | -2,006,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,006,165.
Example:
1 x 2,006,165 = 2,006,165
and
-1 x -2,006,165 = 2,006,165
Notice both answers equal 2,006,165
With that explanation out of the way, let's continue. Next, we take the number 2,006,165 and divide it by 2:
2,006,165 ÷ 2 = 1,003,082.5
If the quotient is a whole number, then 2 and 1,003,082.5 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 | 2,006,165 | |
| -1 | -2,006,165 |
Now, we try dividing 2,006,165 by 3:
2,006,165 ÷ 3 = 668,721.6667
If the quotient is a whole number, then 3 and 668,721.6667 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 | 2,006,165 | |
| -1 | -2,006,165 |
Let's try dividing by 4:
2,006,165 ÷ 4 = 501,541.25
If the quotient is a whole number, then 4 and 501,541.25 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 | 2,006,165 | |
| -1 | 2,006,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 43 | 155 | 215 | 217 | 301 | 1,085 | 1,333 | 1,505 | 1,849 | 6,665 | 9,245 | 9,331 | 12,943 | 46,655 | 57,319 | 64,715 | 286,595 | 401,233 | 2,006,165 |
| -1 | -5 | -7 | -31 | -35 | -43 | -155 | -215 | -217 | -301 | -1,085 | -1,333 | -1,505 | -1,849 | -6,665 | -9,245 | -9,331 | -12,943 | -46,655 | -57,319 | -64,715 | -286,595 | -401,233 | -2,006,165 |
