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 1,790,195, 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 | 1,790,195 | |
| -1 | -1,790,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,790,195.
Example:
1 x 1,790,195 = 1,790,195
and
-1 x -1,790,195 = 1,790,195
Notice both answers equal 1,790,195
With that explanation out of the way, let's continue. Next, we take the number 1,790,195 and divide it by 2:
1,790,195 ÷ 2 = 895,097.5
If the quotient is a whole number, then 2 and 895,097.5 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 | 1,790,195 | |
| -1 | -1,790,195 |
Now, we try dividing 1,790,195 by 3:
1,790,195 ÷ 3 = 596,731.6667
If the quotient is a whole number, then 3 and 596,731.6667 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 | 1,790,195 | |
| -1 | -1,790,195 |
Let's try dividing by 4:
1,790,195 ÷ 4 = 447,548.75
If the quotient is a whole number, then 4 and 447,548.75 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 | 1,790,195 | |
| -1 | 1,790,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 269 | 605 | 1,331 | 1,345 | 2,959 | 6,655 | 14,795 | 32,549 | 162,745 | 358,039 | 1,790,195 |
| -1 | -5 | -11 | -55 | -121 | -269 | -605 | -1,331 | -1,345 | -2,959 | -6,655 | -14,795 | -32,549 | -162,745 | -358,039 | -1,790,195 |
