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 30,223,319, 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 | 30,223,319 | |
| -1 | -30,223,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,223,319.
Example:
1 x 30,223,319 = 30,223,319
and
-1 x -30,223,319 = 30,223,319
Notice both answers equal 30,223,319
With that explanation out of the way, let's continue. Next, we take the number 30,223,319 and divide it by 2:
30,223,319 ÷ 2 = 15,111,659.5
If the quotient is a whole number, then 2 and 15,111,659.5 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 | 30,223,319 | |
| -1 | -30,223,319 |
Now, we try dividing 30,223,319 by 3:
30,223,319 ÷ 3 = 10,074,439.6667
If the quotient is a whole number, then 3 and 10,074,439.6667 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 | 30,223,319 | |
| -1 | -30,223,319 |
Let's try dividing by 4:
30,223,319 ÷ 4 = 7,555,829.75
If the quotient is a whole number, then 4 and 7,555,829.75 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 | 30,223,319 | |
| -1 | 30,223,319 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 113 | 133 | 791 | 2,011 | 2,147 | 14,077 | 15,029 | 38,209 | 227,243 | 267,463 | 1,590,701 | 4,317,617 | 30,223,319 |
| -1 | -7 | -19 | -113 | -133 | -791 | -2,011 | -2,147 | -14,077 | -15,029 | -38,209 | -227,243 | -267,463 | -1,590,701 | -4,317,617 | -30,223,319 |
