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 8,510,185, 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 | 8,510,185 | |
| -1 | -8,510,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,510,185.
Example:
1 x 8,510,185 = 8,510,185
and
-1 x -8,510,185 = 8,510,185
Notice both answers equal 8,510,185
With that explanation out of the way, let's continue. Next, we take the number 8,510,185 and divide it by 2:
8,510,185 ÷ 2 = 4,255,092.5
If the quotient is a whole number, then 2 and 4,255,092.5 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 | 8,510,185 | |
| -1 | -8,510,185 |
Now, we try dividing 8,510,185 by 3:
8,510,185 ÷ 3 = 2,836,728.3333
If the quotient is a whole number, then 3 and 2,836,728.3333 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 | 8,510,185 | |
| -1 | -8,510,185 |
Let's try dividing by 4:
8,510,185 ÷ 4 = 2,127,546.25
If the quotient is a whole number, then 4 and 2,127,546.25 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 | 8,510,185 | |
| -1 | 8,510,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 157 | 185 | 293 | 785 | 1,465 | 5,809 | 10,841 | 29,045 | 46,001 | 54,205 | 230,005 | 1,702,037 | 8,510,185 |
| -1 | -5 | -37 | -157 | -185 | -293 | -785 | -1,465 | -5,809 | -10,841 | -29,045 | -46,001 | -54,205 | -230,005 | -1,702,037 | -8,510,185 |
