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 244,123,411, 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 | 244,123,411 | |
| -1 | -244,123,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,123,411.
Example:
1 x 244,123,411 = 244,123,411
and
-1 x -244,123,411 = 244,123,411
Notice both answers equal 244,123,411
With that explanation out of the way, let's continue. Next, we take the number 244,123,411 and divide it by 2:
244,123,411 ÷ 2 = 122,061,705.5
If the quotient is a whole number, then 2 and 122,061,705.5 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 | 244,123,411 | |
| -1 | -244,123,411 |
Now, we try dividing 244,123,411 by 3:
244,123,411 ÷ 3 = 81,374,470.3333
If the quotient is a whole number, then 3 and 81,374,470.3333 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 | 244,123,411 | |
| -1 | -244,123,411 |
Let's try dividing by 4:
244,123,411 ÷ 4 = 61,030,852.75
If the quotient is a whole number, then 4 and 61,030,852.75 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 | 244,123,411 | |
| -1 | 244,123,411 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 313 | 469 | 1,663 | 2,191 | 11,641 | 20,971 | 111,421 | 146,797 | 520,519 | 779,947 | 3,643,633 | 34,874,773 | 244,123,411 |
| -1 | -7 | -67 | -313 | -469 | -1,663 | -2,191 | -11,641 | -20,971 | -111,421 | -146,797 | -520,519 | -779,947 | -3,643,633 | -34,874,773 | -244,123,411 |
