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 144,330,251, 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 | 144,330,251 | |
| -1 | -144,330,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,330,251.
Example:
1 x 144,330,251 = 144,330,251
and
-1 x -144,330,251 = 144,330,251
Notice both answers equal 144,330,251
With that explanation out of the way, let's continue. Next, we take the number 144,330,251 and divide it by 2:
144,330,251 ÷ 2 = 72,165,125.5
If the quotient is a whole number, then 2 and 72,165,125.5 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 | 144,330,251 | |
| -1 | -144,330,251 |
Now, we try dividing 144,330,251 by 3:
144,330,251 ÷ 3 = 48,110,083.6667
If the quotient is a whole number, then 3 and 48,110,083.6667 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 | 144,330,251 | |
| -1 | -144,330,251 |
Let's try dividing by 4:
144,330,251 ÷ 4 = 36,082,562.75
If the quotient is a whole number, then 4 and 36,082,562.75 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 | 144,330,251 | |
| -1 | 144,330,251 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 167 | 247 | 2,171 | 3,173 | 3,499 | 41,249 | 45,487 | 66,481 | 584,333 | 864,253 | 7,596,329 | 11,102,327 | 144,330,251 |
| -1 | -13 | -19 | -167 | -247 | -2,171 | -3,173 | -3,499 | -41,249 | -45,487 | -66,481 | -584,333 | -864,253 | -7,596,329 | -11,102,327 | -144,330,251 |
