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 144,455,003, 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 | 144,455,003 | |
| -1 | -144,455,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,455,003.
Example:
1 x 144,455,003 = 144,455,003
and
-1 x -144,455,003 = 144,455,003
Notice both answers equal 144,455,003
With that explanation out of the way, let's continue. Next, we take the number 144,455,003 and divide it by 2:
144,455,003 ÷ 2 = 72,227,501.5
If the quotient is a whole number, then 2 and 72,227,501.5 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 | 144,455,003 | |
| -1 | -144,455,003 |
Now, we try dividing 144,455,003 by 3:
144,455,003 ÷ 3 = 48,151,667.6667
If the quotient is a whole number, then 3 and 48,151,667.6667 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 | 144,455,003 | |
| -1 | -144,455,003 |
Let's try dividing by 4:
144,455,003 ÷ 4 = 36,113,750.75
If the quotient is a whole number, then 4 and 36,113,750.75 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 | 144,455,003 | |
| -1 | 144,455,003 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 77 | 121 | 203 | 319 | 847 | 2,233 | 3,509 | 5,881 | 24,563 | 41,167 | 64,691 | 170,549 | 452,837 | 711,601 | 1,193,843 | 1,876,039 | 4,981,207 | 13,132,273 | 20,636,429 | 144,455,003 |
| -1 | -7 | -11 | -29 | -77 | -121 | -203 | -319 | -847 | -2,233 | -3,509 | -5,881 | -24,563 | -41,167 | -64,691 | -170,549 | -452,837 | -711,601 | -1,193,843 | -1,876,039 | -4,981,207 | -13,132,273 | -20,636,429 | -144,455,003 |
