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 144,204,235, 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 | 144,204,235 | |
| -1 | -144,204,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,204,235.
Example:
1 x 144,204,235 = 144,204,235
and
-1 x -144,204,235 = 144,204,235
Notice both answers equal 144,204,235
With that explanation out of the way, let's continue. Next, we take the number 144,204,235 and divide it by 2:
144,204,235 ÷ 2 = 72,102,117.5
If the quotient is a whole number, then 2 and 72,102,117.5 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 | 144,204,235 | |
| -1 | -144,204,235 |
Now, we try dividing 144,204,235 by 3:
144,204,235 ÷ 3 = 48,068,078.3333
If the quotient is a whole number, then 3 and 48,068,078.3333 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 | 144,204,235 | |
| -1 | -144,204,235 |
Let's try dividing by 4:
144,204,235 ÷ 4 = 36,051,058.75
If the quotient is a whole number, then 4 and 36,051,058.75 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 | 144,204,235 | |
| -1 | 144,204,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 239 | 1,195 | 1,673 | 8,365 | 17,239 | 86,195 | 120,673 | 603,365 | 4,120,121 | 20,600,605 | 28,840,847 | 144,204,235 |
| -1 | -5 | -7 | -35 | -239 | -1,195 | -1,673 | -8,365 | -17,239 | -86,195 | -120,673 | -603,365 | -4,120,121 | -20,600,605 | -28,840,847 | -144,204,235 |
