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 161,095, 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 | 161,095 | |
| -1 | -161,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 161,095.
Example:
1 x 161,095 = 161,095
and
-1 x -161,095 = 161,095
Notice both answers equal 161,095
With that explanation out of the way, let's continue. Next, we take the number 161,095 and divide it by 2:
161,095 ÷ 2 = 80,547.5
If the quotient is a whole number, then 2 and 80,547.5 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 | 161,095 | |
| -1 | -161,095 |
Now, we try dividing 161,095 by 3:
161,095 ÷ 3 = 53,698.3333
If the quotient is a whole number, then 3 and 53,698.3333 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 | 161,095 | |
| -1 | -161,095 |
Let's try dividing by 4:
161,095 ÷ 4 = 40,273.75
If the quotient is a whole number, then 4 and 40,273.75 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 | 161,095 | |
| -1 | 161,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 101 | 145 | 319 | 505 | 1,111 | 1,595 | 2,929 | 5,555 | 14,645 | 32,219 | 161,095 |
| -1 | -5 | -11 | -29 | -55 | -101 | -145 | -319 | -505 | -1,111 | -1,595 | -2,929 | -5,555 | -14,645 | -32,219 | -161,095 |
