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 76,687, 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 | 76,687 | |
-1 | -76,687 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,687.
Example:
1 x 76,687 = 76,687
and
-1 x -76,687 = 76,687
Notice both answers equal 76,687
With that explanation out of the way, let's continue. Next, we take the number 76,687 and divide it by 2:
76,687 ÷ 2 = 38,343.5
If the quotient is a whole number, then 2 and 38,343.5 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 | 76,687 | |
-1 | -76,687 |
Now, we try dividing 76,687 by 3:
76,687 ÷ 3 = 25,562.3333
If the quotient is a whole number, then 3 and 25,562.3333 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 | 76,687 | |
-1 | -76,687 |
Let's try dividing by 4:
76,687 ÷ 4 = 19,171.75
If the quotient is a whole number, then 4 and 19,171.75 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 | 76,687 | |
-1 | 76,687 |
If you did it right, you will end up with this table:
1 | 13 | 17 | 221 | 347 | 4,511 | 5,899 | 76,687 |
-1 | -13 | -17 | -221 | -347 | -4,511 | -5,899 | -76,687 |
