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 307,181, 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 | 307,181 | |
-1 | -307,181 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,181.
Example:
1 x 307,181 = 307,181
and
-1 x -307,181 = 307,181
Notice both answers equal 307,181
With that explanation out of the way, let's continue. Next, we take the number 307,181 and divide it by 2:
307,181 ÷ 2 = 153,590.5
If the quotient is a whole number, then 2 and 153,590.5 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 | 307,181 | |
-1 | -307,181 |
Now, we try dividing 307,181 by 3:
307,181 ÷ 3 = 102,393.6667
If the quotient is a whole number, then 3 and 102,393.6667 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 | 307,181 | |
-1 | -307,181 |
Let's try dividing by 4:
307,181 ÷ 4 = 76,795.25
If the quotient is a whole number, then 4 and 76,795.25 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 | 307,181 | |
-1 | 307,181 |
If you did it right, you will end up with this table:
1 | 7 | 49 | 6,269 | 43,883 | 307,181 |
-1 | -7 | -49 | -6,269 | -43,883 | -307,181 |
