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 244,254,365, 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 | 244,254,365 | |
| -1 | -244,254,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,254,365.
Example:
1 x 244,254,365 = 244,254,365
and
-1 x -244,254,365 = 244,254,365
Notice both answers equal 244,254,365
With that explanation out of the way, let's continue. Next, we take the number 244,254,365 and divide it by 2:
244,254,365 ÷ 2 = 122,127,182.5
If the quotient is a whole number, then 2 and 122,127,182.5 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 | 244,254,365 | |
| -1 | -244,254,365 |
Now, we try dividing 244,254,365 by 3:
244,254,365 ÷ 3 = 81,418,121.6667
If the quotient is a whole number, then 3 and 81,418,121.6667 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 | 244,254,365 | |
| -1 | -244,254,365 |
Let's try dividing by 4:
244,254,365 ÷ 4 = 61,063,591.25
If the quotient is a whole number, then 4 and 61,063,591.25 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 | 244,254,365 | |
| -1 | 244,254,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 761 | 2,791 | 3,805 | 13,955 | 17,503 | 64,193 | 87,515 | 320,965 | 2,123,951 | 10,619,755 | 48,850,873 | 244,254,365 |
| -1 | -5 | -23 | -115 | -761 | -2,791 | -3,805 | -13,955 | -17,503 | -64,193 | -87,515 | -320,965 | -2,123,951 | -10,619,755 | -48,850,873 | -244,254,365 |
