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 22,302,113, 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 | 22,302,113 | |
| -1 | -22,302,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,302,113.
Example:
1 x 22,302,113 = 22,302,113
and
-1 x -22,302,113 = 22,302,113
Notice both answers equal 22,302,113
With that explanation out of the way, let's continue. Next, we take the number 22,302,113 and divide it by 2:
22,302,113 ÷ 2 = 11,151,056.5
If the quotient is a whole number, then 2 and 11,151,056.5 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 | 22,302,113 | |
| -1 | -22,302,113 |
Now, we try dividing 22,302,113 by 3:
22,302,113 ÷ 3 = 7,434,037.6667
If the quotient is a whole number, then 3 and 7,434,037.6667 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 | 22,302,113 | |
| -1 | -22,302,113 |
Let's try dividing by 4:
22,302,113 ÷ 4 = 5,575,528.25
If the quotient is a whole number, then 4 and 5,575,528.25 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 | 22,302,113 | |
| -1 | 22,302,113 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 101 | 419 | 527 | 1,717 | 3,131 | 7,123 | 12,989 | 42,319 | 53,227 | 220,813 | 719,423 | 1,311,889 | 22,302,113 |
| -1 | -17 | -31 | -101 | -419 | -527 | -1,717 | -3,131 | -7,123 | -12,989 | -42,319 | -53,227 | -220,813 | -719,423 | -1,311,889 | -22,302,113 |
