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 8,071,175, 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 | 8,071,175 | |
| -1 | -8,071,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,071,175.
Example:
1 x 8,071,175 = 8,071,175
and
-1 x -8,071,175 = 8,071,175
Notice both answers equal 8,071,175
With that explanation out of the way, let's continue. Next, we take the number 8,071,175 and divide it by 2:
8,071,175 ÷ 2 = 4,035,587.5
If the quotient is a whole number, then 2 and 4,035,587.5 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 | 8,071,175 | |
| -1 | -8,071,175 |
Now, we try dividing 8,071,175 by 3:
8,071,175 ÷ 3 = 2,690,391.6667
If the quotient is a whole number, then 3 and 2,690,391.6667 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 | 8,071,175 | |
| -1 | -8,071,175 |
Let's try dividing by 4:
8,071,175 ÷ 4 = 2,017,793.75
If the quotient is a whole number, then 4 and 2,017,793.75 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 | 8,071,175 | |
| -1 | 8,071,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 25 | 35 | 85 | 119 | 175 | 425 | 595 | 2,713 | 2,975 | 13,565 | 18,991 | 46,121 | 67,825 | 94,955 | 230,605 | 322,847 | 474,775 | 1,153,025 | 1,614,235 | 8,071,175 |
| -1 | -5 | -7 | -17 | -25 | -35 | -85 | -119 | -175 | -425 | -595 | -2,713 | -2,975 | -13,565 | -18,991 | -46,121 | -67,825 | -94,955 | -230,605 | -322,847 | -474,775 | -1,153,025 | -1,614,235 | -8,071,175 |
