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 21,933,043, 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 | 21,933,043 | |
| -1 | -21,933,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 21,933,043.
Example:
1 x 21,933,043 = 21,933,043
and
-1 x -21,933,043 = 21,933,043
Notice both answers equal 21,933,043
With that explanation out of the way, let's continue. Next, we take the number 21,933,043 and divide it by 2:
21,933,043 ÷ 2 = 10,966,521.5
If the quotient is a whole number, then 2 and 10,966,521.5 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 | 21,933,043 | |
| -1 | -21,933,043 |
Now, we try dividing 21,933,043 by 3:
21,933,043 ÷ 3 = 7,311,014.3333
If the quotient is a whole number, then 3 and 7,311,014.3333 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 | 21,933,043 | |
| -1 | -21,933,043 |
Let's try dividing by 4:
21,933,043 ÷ 4 = 5,483,260.75
If the quotient is a whole number, then 4 and 5,483,260.75 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 | 21,933,043 | |
| -1 | 21,933,043 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 53 | 187 | 583 | 901 | 2,213 | 9,911 | 24,343 | 37,621 | 117,289 | 413,831 | 1,290,179 | 1,993,913 | 21,933,043 |
| -1 | -11 | -17 | -53 | -187 | -583 | -901 | -2,213 | -9,911 | -24,343 | -37,621 | -117,289 | -413,831 | -1,290,179 | -1,993,913 | -21,933,043 |
