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 102,111,233, 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 | 102,111,233 | |
| -1 | -102,111,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,111,233.
Example:
1 x 102,111,233 = 102,111,233
and
-1 x -102,111,233 = 102,111,233
Notice both answers equal 102,111,233
With that explanation out of the way, let's continue. Next, we take the number 102,111,233 and divide it by 2:
102,111,233 ÷ 2 = 51,055,616.5
If the quotient is a whole number, then 2 and 51,055,616.5 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 | 102,111,233 | |
| -1 | -102,111,233 |
Now, we try dividing 102,111,233 by 3:
102,111,233 ÷ 3 = 34,037,077.6667
If the quotient is a whole number, then 3 and 34,037,077.6667 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 | 102,111,233 | |
| -1 | -102,111,233 |
Let's try dividing by 4:
102,111,233 ÷ 4 = 25,527,808.25
If the quotient is a whole number, then 4 and 25,527,808.25 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 | 102,111,233 | |
| -1 | 102,111,233 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 677 | 743 | 4,739 | 5,201 | 19,633 | 21,547 | 137,431 | 150,829 | 503,011 | 3,521,077 | 14,587,319 | 102,111,233 |
| -1 | -7 | -29 | -203 | -677 | -743 | -4,739 | -5,201 | -19,633 | -21,547 | -137,431 | -150,829 | -503,011 | -3,521,077 | -14,587,319 | -102,111,233 |
