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 131,495, 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 | 131,495 | |
| -1 | -131,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,495.
Example:
1 x 131,495 = 131,495
and
-1 x -131,495 = 131,495
Notice both answers equal 131,495
With that explanation out of the way, let's continue. Next, we take the number 131,495 and divide it by 2:
131,495 ÷ 2 = 65,747.5
If the quotient is a whole number, then 2 and 65,747.5 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 | 131,495 | |
| -1 | -131,495 |
Now, we try dividing 131,495 by 3:
131,495 ÷ 3 = 43,831.6667
If the quotient is a whole number, then 3 and 43,831.6667 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 | 131,495 | |
| -1 | -131,495 |
Let's try dividing by 4:
131,495 ÷ 4 = 32,873.75
If the quotient is a whole number, then 4 and 32,873.75 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 | 131,495 | |
| -1 | 131,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 17 | 35 | 65 | 85 | 91 | 119 | 221 | 289 | 455 | 595 | 1,105 | 1,445 | 1,547 | 2,023 | 3,757 | 7,735 | 10,115 | 18,785 | 26,299 | 131,495 |
| -1 | -5 | -7 | -13 | -17 | -35 | -65 | -85 | -91 | -119 | -221 | -289 | -455 | -595 | -1,105 | -1,445 | -1,547 | -2,023 | -3,757 | -7,735 | -10,115 | -18,785 | -26,299 | -131,495 |
