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 827,365, 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 | 827,365 | |
| -1 | -827,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 827,365.
Example:
1 x 827,365 = 827,365
and
-1 x -827,365 = 827,365
Notice both answers equal 827,365
With that explanation out of the way, let's continue. Next, we take the number 827,365 and divide it by 2:
827,365 ÷ 2 = 413,682.5
If the quotient is a whole number, then 2 and 413,682.5 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 | 827,365 | |
| -1 | -827,365 |
Now, we try dividing 827,365 by 3:
827,365 ÷ 3 = 275,788.3333
If the quotient is a whole number, then 3 and 275,788.3333 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 | 827,365 | |
| -1 | -827,365 |
Let's try dividing by 4:
827,365 ÷ 4 = 206,841.25
If the quotient is a whole number, then 4 and 206,841.25 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 | 827,365 | |
| -1 | 827,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 245 | 307 | 385 | 539 | 1,535 | 2,149 | 2,695 | 3,377 | 10,745 | 15,043 | 16,885 | 23,639 | 75,215 | 118,195 | 165,473 | 827,365 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -245 | -307 | -385 | -539 | -1,535 | -2,149 | -2,695 | -3,377 | -10,745 | -15,043 | -16,885 | -23,639 | -75,215 | -118,195 | -165,473 | -827,365 |
