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 244,420,445, 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 | 244,420,445 | |
| -1 | -244,420,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,420,445.
Example:
1 x 244,420,445 = 244,420,445
and
-1 x -244,420,445 = 244,420,445
Notice both answers equal 244,420,445
With that explanation out of the way, let's continue. Next, we take the number 244,420,445 and divide it by 2:
244,420,445 ÷ 2 = 122,210,222.5
If the quotient is a whole number, then 2 and 122,210,222.5 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 | 244,420,445 | |
| -1 | -244,420,445 |
Now, we try dividing 244,420,445 by 3:
244,420,445 ÷ 3 = 81,473,481.6667
If the quotient is a whole number, then 3 and 81,473,481.6667 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 | 244,420,445 | |
| -1 | -244,420,445 |
Let's try dividing by 4:
244,420,445 ÷ 4 = 61,105,111.25
If the quotient is a whole number, then 4 and 61,105,111.25 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 | 244,420,445 | |
| -1 | 244,420,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 409 | 2,045 | 2,543 | 12,715 | 19,223 | 96,115 | 119,521 | 597,605 | 1,040,087 | 5,200,435 | 48,884,089 | 244,420,445 |
| -1 | -5 | -47 | -235 | -409 | -2,045 | -2,543 | -12,715 | -19,223 | -96,115 | -119,521 | -597,605 | -1,040,087 | -5,200,435 | -48,884,089 | -244,420,445 |
