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 244,455,121, 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 | 244,455,121 | |
| -1 | -244,455,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,455,121.
Example:
1 x 244,455,121 = 244,455,121
and
-1 x -244,455,121 = 244,455,121
Notice both answers equal 244,455,121
With that explanation out of the way, let's continue. Next, we take the number 244,455,121 and divide it by 2:
244,455,121 ÷ 2 = 122,227,560.5
If the quotient is a whole number, then 2 and 122,227,560.5 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 | 244,455,121 | |
| -1 | -244,455,121 |
Now, we try dividing 244,455,121 by 3:
244,455,121 ÷ 3 = 81,485,040.3333
If the quotient is a whole number, then 3 and 81,485,040.3333 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 | 244,455,121 | |
| -1 | -244,455,121 |
Let's try dividing by 4:
244,455,121 ÷ 4 = 61,113,780.25
If the quotient is a whole number, then 4 and 61,113,780.25 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 | 244,455,121 | |
| -1 | 244,455,121 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 61 | 323 | 361 | 653 | 1,037 | 1,159 | 6,137 | 11,101 | 12,407 | 19,703 | 22,021 | 39,833 | 210,919 | 235,733 | 374,357 | 677,161 | 756,827 | 4,007,461 | 12,866,059 | 14,379,713 | 244,455,121 |
| -1 | -17 | -19 | -61 | -323 | -361 | -653 | -1,037 | -1,159 | -6,137 | -11,101 | -12,407 | -19,703 | -22,021 | -39,833 | -210,919 | -235,733 | -374,357 | -677,161 | -756,827 | -4,007,461 | -12,866,059 | -14,379,713 | -244,455,121 |
