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 244,123,529, 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 | 244,123,529 | |
| -1 | -244,123,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,123,529.
Example:
1 x 244,123,529 = 244,123,529
and
-1 x -244,123,529 = 244,123,529
Notice both answers equal 244,123,529
With that explanation out of the way, let's continue. Next, we take the number 244,123,529 and divide it by 2:
244,123,529 ÷ 2 = 122,061,764.5
If the quotient is a whole number, then 2 and 122,061,764.5 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 | 244,123,529 | |
| -1 | -244,123,529 |
Now, we try dividing 244,123,529 by 3:
244,123,529 ÷ 3 = 81,374,509.6667
If the quotient is a whole number, then 3 and 81,374,509.6667 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 | 244,123,529 | |
| -1 | -244,123,529 |
Let's try dividing by 4:
244,123,529 ÷ 4 = 61,030,882.25
If the quotient is a whole number, then 4 and 61,030,882.25 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 | 244,123,529 | |
| -1 | 244,123,529 |
If you did it right, you will end up with this table:
| 1 | 13 | 89 | 257 | 821 | 1,157 | 3,341 | 10,673 | 22,873 | 73,069 | 210,997 | 297,349 | 949,897 | 2,742,961 | 18,778,733 | 244,123,529 |
| -1 | -13 | -89 | -257 | -821 | -1,157 | -3,341 | -10,673 | -22,873 | -73,069 | -210,997 | -297,349 | -949,897 | -2,742,961 | -18,778,733 | -244,123,529 |
