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 144,113,123, 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 | 144,113,123 | |
| -1 | -144,113,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,113,123.
Example:
1 x 144,113,123 = 144,113,123
and
-1 x -144,113,123 = 144,113,123
Notice both answers equal 144,113,123
With that explanation out of the way, let's continue. Next, we take the number 144,113,123 and divide it by 2:
144,113,123 ÷ 2 = 72,056,561.5
If the quotient is a whole number, then 2 and 72,056,561.5 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 | 144,113,123 | |
| -1 | -144,113,123 |
Now, we try dividing 144,113,123 by 3:
144,113,123 ÷ 3 = 48,037,707.6667
If the quotient is a whole number, then 3 and 48,037,707.6667 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 | 144,113,123 | |
| -1 | -144,113,123 |
Let's try dividing by 4:
144,113,123 ÷ 4 = 36,028,280.75
If the quotient is a whole number, then 4 and 36,028,280.75 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 | 144,113,123 | |
| -1 | 144,113,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 127 | 889 | 1,397 | 9,779 | 14,737 | 103,159 | 162,107 | 1,134,749 | 1,871,599 | 13,101,193 | 20,587,589 | 144,113,123 |
| -1 | -7 | -11 | -77 | -127 | -889 | -1,397 | -9,779 | -14,737 | -103,159 | -162,107 | -1,134,749 | -1,871,599 | -13,101,193 | -20,587,589 | -144,113,123 |
