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 22,102,073, 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 | 22,102,073 | |
| -1 | -22,102,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,102,073.
Example:
1 x 22,102,073 = 22,102,073
and
-1 x -22,102,073 = 22,102,073
Notice both answers equal 22,102,073
With that explanation out of the way, let's continue. Next, we take the number 22,102,073 and divide it by 2:
22,102,073 ÷ 2 = 11,051,036.5
If the quotient is a whole number, then 2 and 11,051,036.5 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 | 22,102,073 | |
| -1 | -22,102,073 |
Now, we try dividing 22,102,073 by 3:
22,102,073 ÷ 3 = 7,367,357.6667
If the quotient is a whole number, then 3 and 7,367,357.6667 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 | 22,102,073 | |
| -1 | -22,102,073 |
Let's try dividing by 4:
22,102,073 ÷ 4 = 5,525,518.25
If the quotient is a whole number, then 4 and 5,525,518.25 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 | 22,102,073 | |
| -1 | 22,102,073 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 137 | 959 | 1,213 | 2,603 | 8,491 | 18,221 | 23,047 | 161,329 | 166,181 | 1,163,267 | 3,157,439 | 22,102,073 |
| -1 | -7 | -19 | -133 | -137 | -959 | -1,213 | -2,603 | -8,491 | -18,221 | -23,047 | -161,329 | -166,181 | -1,163,267 | -3,157,439 | -22,102,073 |
