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 144,541,241, 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 | 144,541,241 | |
| -1 | -144,541,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,541,241.
Example:
1 x 144,541,241 = 144,541,241
and
-1 x -144,541,241 = 144,541,241
Notice both answers equal 144,541,241
With that explanation out of the way, let's continue. Next, we take the number 144,541,241 and divide it by 2:
144,541,241 ÷ 2 = 72,270,620.5
If the quotient is a whole number, then 2 and 72,270,620.5 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 | 144,541,241 | |
| -1 | -144,541,241 |
Now, we try dividing 144,541,241 by 3:
144,541,241 ÷ 3 = 48,180,413.6667
If the quotient is a whole number, then 3 and 48,180,413.6667 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 | 144,541,241 | |
| -1 | -144,541,241 |
Let's try dividing by 4:
144,541,241 ÷ 4 = 36,135,310.25
If the quotient is a whole number, then 4 and 36,135,310.25 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 | 144,541,241 | |
| -1 | 144,541,241 |
If you did it right, you will end up with this table:
| 1 | 13 | 73 | 223 | 683 | 949 | 2,899 | 8,879 | 16,279 | 49,859 | 152,309 | 211,627 | 648,167 | 1,980,017 | 11,118,557 | 144,541,241 |
| -1 | -13 | -73 | -223 | -683 | -949 | -2,899 | -8,879 | -16,279 | -49,859 | -152,309 | -211,627 | -648,167 | -1,980,017 | -11,118,557 | -144,541,241 |
