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 1,933,393, 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 | 1,933,393 | |
| -1 | -1,933,393 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,933,393.
Example:
1 x 1,933,393 = 1,933,393
and
-1 x -1,933,393 = 1,933,393
Notice both answers equal 1,933,393
With that explanation out of the way, let's continue. Next, we take the number 1,933,393 and divide it by 2:
1,933,393 ÷ 2 = 966,696.5
If the quotient is a whole number, then 2 and 966,696.5 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 | 1,933,393 | |
| -1 | -1,933,393 |
Now, we try dividing 1,933,393 by 3:
1,933,393 ÷ 3 = 644,464.3333
If the quotient is a whole number, then 3 and 644,464.3333 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 | 1,933,393 | |
| -1 | -1,933,393 |
Let's try dividing by 4:
1,933,393 ÷ 4 = 483,348.25
If the quotient is a whole number, then 4 and 483,348.25 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 | 1,933,393 | |
| -1 | 1,933,393 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 49 | 77 | 119 | 187 | 211 | 539 | 833 | 1,309 | 1,477 | 2,321 | 3,587 | 9,163 | 10,339 | 16,247 | 25,109 | 39,457 | 113,729 | 175,763 | 276,199 | 1,933,393 |
| -1 | -7 | -11 | -17 | -49 | -77 | -119 | -187 | -211 | -539 | -833 | -1,309 | -1,477 | -2,321 | -3,587 | -9,163 | -10,339 | -16,247 | -25,109 | -39,457 | -113,729 | -175,763 | -276,199 | -1,933,393 |
