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 57,817, 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 | 57,817 | |
-1 | -57,817 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,817.
Example:
1 x 57,817 = 57,817
and
-1 x -57,817 = 57,817
Notice both answers equal 57,817
With that explanation out of the way, let's continue. Next, we take the number 57,817 and divide it by 2:
57,817 ÷ 2 = 28,908.5
If the quotient is a whole number, then 2 and 28,908.5 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 | 57,817 | |
-1 | -57,817 |
Now, we try dividing 57,817 by 3:
57,817 ÷ 3 = 19,272.3333
If the quotient is a whole number, then 3 and 19,272.3333 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 | 57,817 | |
-1 | -57,817 |
Let's try dividing by 4:
57,817 ÷ 4 = 14,454.25
If the quotient is a whole number, then 4 and 14,454.25 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 | 57,817 | |
-1 | 57,817 |
If you did it right, you will end up with this table:
1 | 17 | 19 | 179 | 323 | 3,043 | 3,401 | 57,817 |
-1 | -17 | -19 | -179 | -323 | -3,043 | -3,401 | -57,817 |
