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 245,333,111, 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 | 245,333,111 | |
| -1 | -245,333,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,333,111.
Example:
1 x 245,333,111 = 245,333,111
and
-1 x -245,333,111 = 245,333,111
Notice both answers equal 245,333,111
With that explanation out of the way, let's continue. Next, we take the number 245,333,111 and divide it by 2:
245,333,111 ÷ 2 = 122,666,555.5
If the quotient is a whole number, then 2 and 122,666,555.5 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 | 245,333,111 | |
| -1 | -245,333,111 |
Now, we try dividing 245,333,111 by 3:
245,333,111 ÷ 3 = 81,777,703.6667
If the quotient is a whole number, then 3 and 81,777,703.6667 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 | 245,333,111 | |
| -1 | -245,333,111 |
Let's try dividing by 4:
245,333,111 ÷ 4 = 61,333,277.75
If the quotient is a whole number, then 4 and 61,333,277.75 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 | 245,333,111 | |
| -1 | 245,333,111 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 269 | 437 | 2,087 | 5,111 | 6,187 | 39,653 | 48,001 | 117,553 | 561,403 | 912,019 | 10,666,657 | 12,912,269 | 245,333,111 |
| -1 | -19 | -23 | -269 | -437 | -2,087 | -5,111 | -6,187 | -39,653 | -48,001 | -117,553 | -561,403 | -912,019 | -10,666,657 | -12,912,269 | -245,333,111 |
