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 144,242,357, 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 | 144,242,357 | |
| -1 | -144,242,357 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,242,357.
Example:
1 x 144,242,357 = 144,242,357
and
-1 x -144,242,357 = 144,242,357
Notice both answers equal 144,242,357
With that explanation out of the way, let's continue. Next, we take the number 144,242,357 and divide it by 2:
144,242,357 ÷ 2 = 72,121,178.5
If the quotient is a whole number, then 2 and 72,121,178.5 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 | 144,242,357 | |
| -1 | -144,242,357 |
Now, we try dividing 144,242,357 by 3:
144,242,357 ÷ 3 = 48,080,785.6667
If the quotient is a whole number, then 3 and 48,080,785.6667 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 | 144,242,357 | |
| -1 | -144,242,357 |
Let's try dividing by 4:
144,242,357 ÷ 4 = 36,060,589.25
If the quotient is a whole number, then 4 and 36,060,589.25 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 | 144,242,357 | |
| -1 | 144,242,357 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 67 | 133 | 469 | 1,273 | 8,911 | 16,187 | 113,309 | 307,553 | 1,084,529 | 2,152,871 | 7,591,703 | 20,606,051 | 144,242,357 |
| -1 | -7 | -19 | -67 | -133 | -469 | -1,273 | -8,911 | -16,187 | -113,309 | -307,553 | -1,084,529 | -2,152,871 | -7,591,703 | -20,606,051 | -144,242,357 |
