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 1,661,699, 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 | 1,661,699 | |
| -1 | -1,661,699 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,661,699.
Example:
1 x 1,661,699 = 1,661,699
and
-1 x -1,661,699 = 1,661,699
Notice both answers equal 1,661,699
With that explanation out of the way, let's continue. Next, we take the number 1,661,699 and divide it by 2:
1,661,699 ÷ 2 = 830,849.5
If the quotient is a whole number, then 2 and 830,849.5 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 | 1,661,699 | |
| -1 | -1,661,699 |
Now, we try dividing 1,661,699 by 3:
1,661,699 ÷ 3 = 553,899.6667
If the quotient is a whole number, then 3 and 553,899.6667 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 | 1,661,699 | |
| -1 | -1,661,699 |
Let's try dividing by 4:
1,661,699 ÷ 4 = 415,424.75
If the quotient is a whole number, then 4 and 415,424.75 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 | 1,661,699 | |
| -1 | 1,661,699 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 73 | 103 | 221 | 949 | 1,241 | 1,339 | 1,751 | 7,519 | 16,133 | 22,763 | 97,747 | 127,823 | 1,661,699 |
| -1 | -13 | -17 | -73 | -103 | -221 | -949 | -1,241 | -1,339 | -1,751 | -7,519 | -16,133 | -22,763 | -97,747 | -127,823 | -1,661,699 |
