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 144,332,113, 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 | 144,332,113 | |
| -1 | -144,332,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,332,113.
Example:
1 x 144,332,113 = 144,332,113
and
-1 x -144,332,113 = 144,332,113
Notice both answers equal 144,332,113
With that explanation out of the way, let's continue. Next, we take the number 144,332,113 and divide it by 2:
144,332,113 ÷ 2 = 72,166,056.5
If the quotient is a whole number, then 2 and 72,166,056.5 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 | 144,332,113 | |
| -1 | -144,332,113 |
Now, we try dividing 144,332,113 by 3:
144,332,113 ÷ 3 = 48,110,704.3333
If the quotient is a whole number, then 3 and 48,110,704.3333 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 | 144,332,113 | |
| -1 | -144,332,113 |
Let's try dividing by 4:
144,332,113 ÷ 4 = 36,083,028.25
If the quotient is a whole number, then 4 and 36,083,028.25 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 | 144,332,113 | |
| -1 | 144,332,113 |
If you did it right, you will end up with this table:
| 1 | 19 | 59 | 199 | 647 | 1,121 | 3,781 | 11,741 | 12,293 | 38,173 | 128,753 | 223,079 | 725,287 | 2,446,307 | 7,596,427 | 144,332,113 |
| -1 | -19 | -59 | -199 | -647 | -1,121 | -3,781 | -11,741 | -12,293 | -38,173 | -128,753 | -223,079 | -725,287 | -2,446,307 | -7,596,427 | -144,332,113 |
