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 66,305, 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 | 66,305 | |
-1 | -66,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,305.
Example:
1 x 66,305 = 66,305
and
-1 x -66,305 = 66,305
Notice both answers equal 66,305
With that explanation out of the way, let's continue. Next, we take the number 66,305 and divide it by 2:
66,305 ÷ 2 = 33,152.5
If the quotient is a whole number, then 2 and 33,152.5 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 | 66,305 | |
-1 | -66,305 |
Now, we try dividing 66,305 by 3:
66,305 ÷ 3 = 22,101.6667
If the quotient is a whole number, then 3 and 22,101.6667 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 | 66,305 | |
-1 | -66,305 |
Let's try dividing by 4:
66,305 ÷ 4 = 16,576.25
If the quotient is a whole number, then 4 and 16,576.25 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 | 66,305 | |
-1 | 66,305 |
If you did it right, you will end up with this table:
1 | 5 | 89 | 149 | 445 | 745 | 13,261 | 66,305 |
-1 | -5 | -89 | -149 | -445 | -745 | -13,261 | -66,305 |
