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 1,690,799, 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 | 1,690,799 | |
| -1 | -1,690,799 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,690,799.
Example:
1 x 1,690,799 = 1,690,799
and
-1 x -1,690,799 = 1,690,799
Notice both answers equal 1,690,799
With that explanation out of the way, let's continue. Next, we take the number 1,690,799 and divide it by 2:
1,690,799 ÷ 2 = 845,399.5
If the quotient is a whole number, then 2 and 845,399.5 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 | 1,690,799 | |
| -1 | -1,690,799 |
Now, we try dividing 1,690,799 by 3:
1,690,799 ÷ 3 = 563,599.6667
If the quotient is a whole number, then 3 and 563,599.6667 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 | 1,690,799 | |
| -1 | -1,690,799 |
Let's try dividing by 4:
1,690,799 ÷ 4 = 422,699.75
If the quotient is a whole number, then 4 and 422,699.75 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 | 1,690,799 | |
| -1 | 1,690,799 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 41 | 163 | 253 | 451 | 943 | 1,793 | 3,749 | 6,683 | 10,373 | 41,239 | 73,513 | 153,709 | 1,690,799 |
| -1 | -11 | -23 | -41 | -163 | -253 | -451 | -943 | -1,793 | -3,749 | -6,683 | -10,373 | -41,239 | -73,513 | -153,709 | -1,690,799 |
