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 244,021,243, 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 | 244,021,243 | |
| -1 | -244,021,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,021,243.
Example:
1 x 244,021,243 = 244,021,243
and
-1 x -244,021,243 = 244,021,243
Notice both answers equal 244,021,243
With that explanation out of the way, let's continue. Next, we take the number 244,021,243 and divide it by 2:
244,021,243 ÷ 2 = 122,010,621.5
If the quotient is a whole number, then 2 and 122,010,621.5 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 | 244,021,243 | |
| -1 | -244,021,243 |
Now, we try dividing 244,021,243 by 3:
244,021,243 ÷ 3 = 81,340,414.3333
If the quotient is a whole number, then 3 and 81,340,414.3333 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 | 244,021,243 | |
| -1 | -244,021,243 |
Let's try dividing by 4:
244,021,243 ÷ 4 = 61,005,310.75
If the quotient is a whole number, then 4 and 61,005,310.75 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 | 244,021,243 | |
| -1 | 244,021,243 |
If you did it right, you will end up with this table:
| 1 | 31 | 109 | 257 | 281 | 3,379 | 7,967 | 8,711 | 28,013 | 30,629 | 72,217 | 868,403 | 949,499 | 2,238,727 | 7,871,653 | 244,021,243 |
| -1 | -31 | -109 | -257 | -281 | -3,379 | -7,967 | -8,711 | -28,013 | -30,629 | -72,217 | -868,403 | -949,499 | -2,238,727 | -7,871,653 | -244,021,243 |
