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 22,300,243, 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 | 22,300,243 | |
| -1 | -22,300,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,300,243.
Example:
1 x 22,300,243 = 22,300,243
and
-1 x -22,300,243 = 22,300,243
Notice both answers equal 22,300,243
With that explanation out of the way, let's continue. Next, we take the number 22,300,243 and divide it by 2:
22,300,243 ÷ 2 = 11,150,121.5
If the quotient is a whole number, then 2 and 11,150,121.5 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 | 22,300,243 | |
| -1 | -22,300,243 |
Now, we try dividing 22,300,243 by 3:
22,300,243 ÷ 3 = 7,433,414.3333
If the quotient is a whole number, then 3 and 7,433,414.3333 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 | 22,300,243 | |
| -1 | -22,300,243 |
Let's try dividing by 4:
22,300,243 ÷ 4 = 5,575,060.75
If the quotient is a whole number, then 4 and 5,575,060.75 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 | 22,300,243 | |
| -1 | 22,300,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 49 | 119 | 133 | 323 | 833 | 931 | 1,409 | 2,261 | 9,863 | 15,827 | 23,953 | 26,771 | 69,041 | 167,671 | 187,397 | 455,107 | 1,173,697 | 1,311,779 | 3,185,749 | 22,300,243 |
| -1 | -7 | -17 | -19 | -49 | -119 | -133 | -323 | -833 | -931 | -1,409 | -2,261 | -9,863 | -15,827 | -23,953 | -26,771 | -69,041 | -167,671 | -187,397 | -455,107 | -1,173,697 | -1,311,779 | -3,185,749 | -22,300,243 |
