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 144,127,477, 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 | 144,127,477 | |
| -1 | -144,127,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,127,477.
Example:
1 x 144,127,477 = 144,127,477
and
-1 x -144,127,477 = 144,127,477
Notice both answers equal 144,127,477
With that explanation out of the way, let's continue. Next, we take the number 144,127,477 and divide it by 2:
144,127,477 ÷ 2 = 72,063,738.5
If the quotient is a whole number, then 2 and 72,063,738.5 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 | 144,127,477 | |
| -1 | -144,127,477 |
Now, we try dividing 144,127,477 by 3:
144,127,477 ÷ 3 = 48,042,492.3333
If the quotient is a whole number, then 3 and 48,042,492.3333 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 | 144,127,477 | |
| -1 | -144,127,477 |
Let's try dividing by 4:
144,127,477 ÷ 4 = 36,031,869.25
If the quotient is a whole number, then 4 and 36,031,869.25 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 | 144,127,477 | |
| -1 | 144,127,477 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 73 | 377 | 949 | 2,117 | 5,237 | 27,521 | 68,081 | 151,873 | 382,301 | 1,974,349 | 4,969,913 | 11,086,729 | 144,127,477 |
| -1 | -13 | -29 | -73 | -377 | -949 | -2,117 | -5,237 | -27,521 | -68,081 | -151,873 | -382,301 | -1,974,349 | -4,969,913 | -11,086,729 | -144,127,477 |
