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 2,006,095, 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 | 2,006,095 | |
| -1 | -2,006,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,006,095.
Example:
1 x 2,006,095 = 2,006,095
and
-1 x -2,006,095 = 2,006,095
Notice both answers equal 2,006,095
With that explanation out of the way, let's continue. Next, we take the number 2,006,095 and divide it by 2:
2,006,095 ÷ 2 = 1,003,047.5
If the quotient is a whole number, then 2 and 1,003,047.5 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 | 2,006,095 | |
| -1 | -2,006,095 |
Now, we try dividing 2,006,095 by 3:
2,006,095 ÷ 3 = 668,698.3333
If the quotient is a whole number, then 3 and 668,698.3333 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 | 2,006,095 | |
| -1 | -2,006,095 |
Let's try dividing by 4:
2,006,095 ÷ 4 = 501,523.75
If the quotient is a whole number, then 4 and 501,523.75 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 | 2,006,095 | |
| -1 | 2,006,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 4,409 | 22,045 | 30,863 | 57,317 | 154,315 | 286,585 | 401,219 | 2,006,095 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -4,409 | -22,045 | -30,863 | -57,317 | -154,315 | -286,585 | -401,219 | -2,006,095 |
