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 64,885, 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 | 64,885 | |
-1 | -64,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,885.
Example:
1 x 64,885 = 64,885
and
-1 x -64,885 = 64,885
Notice both answers equal 64,885
With that explanation out of the way, let's continue. Next, we take the number 64,885 and divide it by 2:
64,885 ÷ 2 = 32,442.5
If the quotient is a whole number, then 2 and 32,442.5 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 | 64,885 | |
-1 | -64,885 |
Now, we try dividing 64,885 by 3:
64,885 ÷ 3 = 21,628.3333
If the quotient is a whole number, then 3 and 21,628.3333 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 | 64,885 | |
-1 | -64,885 |
Let's try dividing by 4:
64,885 ÷ 4 = 16,221.25
If the quotient is a whole number, then 4 and 16,221.25 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 | 64,885 | |
-1 | 64,885 |
If you did it right, you will end up with this table:
1 | 5 | 19 | 95 | 683 | 3,415 | 12,977 | 64,885 |
-1 | -5 | -19 | -95 | -683 | -3,415 | -12,977 | -64,885 |
