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 144,305, 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 | 144,305 | |
| -1 | -144,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,305.
Example:
1 x 144,305 = 144,305
and
-1 x -144,305 = 144,305
Notice both answers equal 144,305
With that explanation out of the way, let's continue. Next, we take the number 144,305 and divide it by 2:
144,305 ÷ 2 = 72,152.5
If the quotient is a whole number, then 2 and 72,152.5 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 | 144,305 | |
| -1 | -144,305 |
Now, we try dividing 144,305 by 3:
144,305 ÷ 3 = 48,101.6667
If the quotient is a whole number, then 3 and 48,101.6667 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 | 144,305 | |
| -1 | -144,305 |
Let's try dividing by 4:
144,305 ÷ 4 = 36,076.25
If the quotient is a whole number, then 4 and 36,076.25 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 | 144,305 | |
| -1 | 144,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 31 | 35 | 49 | 95 | 133 | 155 | 217 | 245 | 589 | 665 | 931 | 1,085 | 1,519 | 2,945 | 4,123 | 4,655 | 7,595 | 20,615 | 28,861 | 144,305 |
| -1 | -5 | -7 | -19 | -31 | -35 | -49 | -95 | -133 | -155 | -217 | -245 | -589 | -665 | -931 | -1,085 | -1,519 | -2,945 | -4,123 | -4,655 | -7,595 | -20,615 | -28,861 | -144,305 |
