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 828,971, 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 | 828,971 | |
| -1 | -828,971 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 828,971.
Example:
1 x 828,971 = 828,971
and
-1 x -828,971 = 828,971
Notice both answers equal 828,971
With that explanation out of the way, let's continue. Next, we take the number 828,971 and divide it by 2:
828,971 ÷ 2 = 414,485.5
If the quotient is a whole number, then 2 and 414,485.5 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 | 828,971 | |
| -1 | -828,971 |
Now, we try dividing 828,971 by 3:
828,971 ÷ 3 = 276,323.6667
If the quotient is a whole number, then 3 and 276,323.6667 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 | 828,971 | |
| -1 | -828,971 |
Let's try dividing by 4:
828,971 ÷ 4 = 207,242.75
If the quotient is a whole number, then 4 and 207,242.75 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 | 828,971 | |
| -1 | 828,971 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 31 | 121 | 143 | 187 | 221 | 341 | 403 | 527 | 1,573 | 2,057 | 2,431 | 3,751 | 4,433 | 5,797 | 6,851 | 26,741 | 48,763 | 63,767 | 75,361 | 828,971 |
| -1 | -11 | -13 | -17 | -31 | -121 | -143 | -187 | -221 | -341 | -403 | -527 | -1,573 | -2,057 | -2,431 | -3,751 | -4,433 | -5,797 | -6,851 | -26,741 | -48,763 | -63,767 | -75,361 | -828,971 |
