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 144,007,825, 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 | 144,007,825 | |
| -1 | -144,007,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,007,825.
Example:
1 x 144,007,825 = 144,007,825
and
-1 x -144,007,825 = 144,007,825
Notice both answers equal 144,007,825
With that explanation out of the way, let's continue. Next, we take the number 144,007,825 and divide it by 2:
144,007,825 ÷ 2 = 72,003,912.5
If the quotient is a whole number, then 2 and 72,003,912.5 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 | 144,007,825 | |
| -1 | -144,007,825 |
Now, we try dividing 144,007,825 by 3:
144,007,825 ÷ 3 = 48,002,608.3333
If the quotient is a whole number, then 3 and 48,002,608.3333 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 | 144,007,825 | |
| -1 | -144,007,825 |
Let's try dividing by 4:
144,007,825 ÷ 4 = 36,001,956.25
If the quotient is a whole number, then 4 and 36,001,956.25 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 | 144,007,825 | |
| -1 | 144,007,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 223 | 325 | 1,115 | 1,987 | 2,899 | 5,575 | 9,935 | 14,495 | 25,831 | 49,675 | 72,475 | 129,155 | 443,101 | 645,775 | 2,215,505 | 5,760,313 | 11,077,525 | 28,801,565 | 144,007,825 |
| -1 | -5 | -13 | -25 | -65 | -223 | -325 | -1,115 | -1,987 | -2,899 | -5,575 | -9,935 | -14,495 | -25,831 | -49,675 | -72,475 | -129,155 | -443,101 | -645,775 | -2,215,505 | -5,760,313 | -11,077,525 | -28,801,565 | -144,007,825 |
