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 244,416,745, 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 | 244,416,745 | |
| -1 | -244,416,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,416,745.
Example:
1 x 244,416,745 = 244,416,745
and
-1 x -244,416,745 = 244,416,745
Notice both answers equal 244,416,745
With that explanation out of the way, let's continue. Next, we take the number 244,416,745 and divide it by 2:
244,416,745 ÷ 2 = 122,208,372.5
If the quotient is a whole number, then 2 and 122,208,372.5 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 | 244,416,745 | |
| -1 | -244,416,745 |
Now, we try dividing 244,416,745 by 3:
244,416,745 ÷ 3 = 81,472,248.3333
If the quotient is a whole number, then 3 and 81,472,248.3333 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 | 244,416,745 | |
| -1 | -244,416,745 |
Let's try dividing by 4:
244,416,745 ÷ 4 = 61,104,186.25
If the quotient is a whole number, then 4 and 61,104,186.25 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 | 244,416,745 | |
| -1 | 244,416,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 911 | 2,333 | 4,555 | 11,665 | 20,953 | 53,659 | 104,765 | 268,295 | 2,125,363 | 10,626,815 | 48,883,349 | 244,416,745 |
| -1 | -5 | -23 | -115 | -911 | -2,333 | -4,555 | -11,665 | -20,953 | -53,659 | -104,765 | -268,295 | -2,125,363 | -10,626,815 | -48,883,349 | -244,416,745 |
