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 144,505,241, 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 | 144,505,241 | |
| -1 | -144,505,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,505,241.
Example:
1 x 144,505,241 = 144,505,241
and
-1 x -144,505,241 = 144,505,241
Notice both answers equal 144,505,241
With that explanation out of the way, let's continue. Next, we take the number 144,505,241 and divide it by 2:
144,505,241 ÷ 2 = 72,252,620.5
If the quotient is a whole number, then 2 and 72,252,620.5 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 | 144,505,241 | |
| -1 | -144,505,241 |
Now, we try dividing 144,505,241 by 3:
144,505,241 ÷ 3 = 48,168,413.6667
If the quotient is a whole number, then 3 and 48,168,413.6667 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 | 144,505,241 | |
| -1 | -144,505,241 |
Let's try dividing by 4:
144,505,241 ÷ 4 = 36,126,310.25
If the quotient is a whole number, then 4 and 36,126,310.25 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 | 144,505,241 | |
| -1 | 144,505,241 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 83 | 817 | 1,577 | 2,131 | 3,569 | 40,489 | 67,811 | 91,633 | 176,873 | 1,741,027 | 3,360,587 | 7,605,539 | 144,505,241 |
| -1 | -19 | -43 | -83 | -817 | -1,577 | -2,131 | -3,569 | -40,489 | -67,811 | -91,633 | -176,873 | -1,741,027 | -3,360,587 | -7,605,539 | -144,505,241 |
