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 131,461,165, 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 | 131,461,165 | |
| -1 | -131,461,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,461,165.
Example:
1 x 131,461,165 = 131,461,165
and
-1 x -131,461,165 = 131,461,165
Notice both answers equal 131,461,165
With that explanation out of the way, let's continue. Next, we take the number 131,461,165 and divide it by 2:
131,461,165 ÷ 2 = 65,730,582.5
If the quotient is a whole number, then 2 and 65,730,582.5 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 | 131,461,165 | |
| -1 | -131,461,165 |
Now, we try dividing 131,461,165 by 3:
131,461,165 ÷ 3 = 43,820,388.3333
If the quotient is a whole number, then 3 and 43,820,388.3333 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 | 131,461,165 | |
| -1 | -131,461,165 |
Let's try dividing by 4:
131,461,165 ÷ 4 = 32,865,291.25
If the quotient is a whole number, then 4 and 32,865,291.25 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 | 131,461,165 | |
| -1 | 131,461,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 797 | 2,999 | 3,985 | 8,767 | 14,995 | 32,989 | 43,835 | 164,945 | 2,390,203 | 11,951,015 | 26,292,233 | 131,461,165 |
| -1 | -5 | -11 | -55 | -797 | -2,999 | -3,985 | -8,767 | -14,995 | -32,989 | -43,835 | -164,945 | -2,390,203 | -11,951,015 | -26,292,233 | -131,461,165 |
