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 1,950,665, 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 | 1,950,665 | |
| -1 | -1,950,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,950,665.
Example:
1 x 1,950,665 = 1,950,665
and
-1 x -1,950,665 = 1,950,665
Notice both answers equal 1,950,665
With that explanation out of the way, let's continue. Next, we take the number 1,950,665 and divide it by 2:
1,950,665 ÷ 2 = 975,332.5
If the quotient is a whole number, then 2 and 975,332.5 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 | 1,950,665 | |
| -1 | -1,950,665 |
Now, we try dividing 1,950,665 by 3:
1,950,665 ÷ 3 = 650,221.6667
If the quotient is a whole number, then 3 and 650,221.6667 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 | 1,950,665 | |
| -1 | -1,950,665 |
Let's try dividing by 4:
1,950,665 ÷ 4 = 487,666.25
If the quotient is a whole number, then 4 and 487,666.25 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 | 1,950,665 | |
| -1 | 1,950,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 53 | 85 | 265 | 433 | 901 | 2,165 | 4,505 | 7,361 | 22,949 | 36,805 | 114,745 | 390,133 | 1,950,665 |
| -1 | -5 | -17 | -53 | -85 | -265 | -433 | -901 | -2,165 | -4,505 | -7,361 | -22,949 | -36,805 | -114,745 | -390,133 | -1,950,665 |
