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 144,311,405, 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 | 144,311,405 | |
| -1 | -144,311,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,311,405.
Example:
1 x 144,311,405 = 144,311,405
and
-1 x -144,311,405 = 144,311,405
Notice both answers equal 144,311,405
With that explanation out of the way, let's continue. Next, we take the number 144,311,405 and divide it by 2:
144,311,405 ÷ 2 = 72,155,702.5
If the quotient is a whole number, then 2 and 72,155,702.5 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 | 144,311,405 | |
| -1 | -144,311,405 |
Now, we try dividing 144,311,405 by 3:
144,311,405 ÷ 3 = 48,103,801.6667
If the quotient is a whole number, then 3 and 48,103,801.6667 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 | 144,311,405 | |
| -1 | -144,311,405 |
Let's try dividing by 4:
144,311,405 ÷ 4 = 36,077,851.25
If the quotient is a whole number, then 4 and 36,077,851.25 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 | 144,311,405 | |
| -1 | 144,311,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 2,485 | 58,073 | 290,365 | 406,511 | 2,032,555 | 4,123,183 | 20,615,915 | 28,862,281 | 144,311,405 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -2,485 | -58,073 | -290,365 | -406,511 | -2,032,555 | -4,123,183 | -20,615,915 | -28,862,281 | -144,311,405 |
