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 243,326,111, 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 | 243,326,111 | |
| -1 | -243,326,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 243,326,111.
Example:
1 x 243,326,111 = 243,326,111
and
-1 x -243,326,111 = 243,326,111
Notice both answers equal 243,326,111
With that explanation out of the way, let's continue. Next, we take the number 243,326,111 and divide it by 2:
243,326,111 ÷ 2 = 121,663,055.5
If the quotient is a whole number, then 2 and 121,663,055.5 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 | 243,326,111 | |
| -1 | -243,326,111 |
Now, we try dividing 243,326,111 by 3:
243,326,111 ÷ 3 = 81,108,703.6667
If the quotient is a whole number, then 3 and 81,108,703.6667 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 | 243,326,111 | |
| -1 | -243,326,111 |
Let's try dividing by 4:
243,326,111 ÷ 4 = 60,831,527.75
If the quotient is a whole number, then 4 and 60,831,527.75 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 | 243,326,111 | |
| -1 | 243,326,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 67 | 137 | 469 | 541 | 959 | 3,283 | 3,787 | 6,713 | 9,179 | 26,509 | 36,247 | 64,253 | 74,117 | 253,729 | 449,771 | 518,819 | 1,776,103 | 3,631,733 | 4,965,839 | 34,760,873 | 243,326,111 |
| -1 | -7 | -49 | -67 | -137 | -469 | -541 | -959 | -3,283 | -3,787 | -6,713 | -9,179 | -26,509 | -36,247 | -64,253 | -74,117 | -253,729 | -449,771 | -518,819 | -1,776,103 | -3,631,733 | -4,965,839 | -34,760,873 | -243,326,111 |
