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 1,973,321, 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 | 1,973,321 | |
| -1 | -1,973,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,973,321.
Example:
1 x 1,973,321 = 1,973,321
and
-1 x -1,973,321 = 1,973,321
Notice both answers equal 1,973,321
With that explanation out of the way, let's continue. Next, we take the number 1,973,321 and divide it by 2:
1,973,321 ÷ 2 = 986,660.5
If the quotient is a whole number, then 2 and 986,660.5 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 | 1,973,321 | |
| -1 | -1,973,321 |
Now, we try dividing 1,973,321 by 3:
1,973,321 ÷ 3 = 657,773.6667
If the quotient is a whole number, then 3 and 657,773.6667 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 | 1,973,321 | |
| -1 | -1,973,321 |
Let's try dividing by 4:
1,973,321 ÷ 4 = 493,330.25
If the quotient is a whole number, then 4 and 493,330.25 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 | 1,973,321 | |
| -1 | 1,973,321 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 37 | 133 | 259 | 401 | 703 | 2,807 | 4,921 | 7,619 | 14,837 | 53,333 | 103,859 | 281,903 | 1,973,321 |
| -1 | -7 | -19 | -37 | -133 | -259 | -401 | -703 | -2,807 | -4,921 | -7,619 | -14,837 | -53,333 | -103,859 | -281,903 | -1,973,321 |
