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 8,495,015, 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 | 8,495,015 | |
| -1 | -8,495,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,495,015.
Example:
1 x 8,495,015 = 8,495,015
and
-1 x -8,495,015 = 8,495,015
Notice both answers equal 8,495,015
With that explanation out of the way, let's continue. Next, we take the number 8,495,015 and divide it by 2:
8,495,015 ÷ 2 = 4,247,507.5
If the quotient is a whole number, then 2 and 4,247,507.5 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 | 8,495,015 | |
| -1 | -8,495,015 |
Now, we try dividing 8,495,015 by 3:
8,495,015 ÷ 3 = 2,831,671.6667
If the quotient is a whole number, then 3 and 2,831,671.6667 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 | 8,495,015 | |
| -1 | -8,495,015 |
Let's try dividing by 4:
8,495,015 ÷ 4 = 2,123,753.75
If the quotient is a whole number, then 4 and 2,123,753.75 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 | 8,495,015 | |
| -1 | 8,495,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 47 | 185 | 235 | 977 | 1,739 | 4,885 | 8,695 | 36,149 | 45,919 | 180,745 | 229,595 | 1,699,003 | 8,495,015 |
| -1 | -5 | -37 | -47 | -185 | -235 | -977 | -1,739 | -4,885 | -8,695 | -36,149 | -45,919 | -180,745 | -229,595 | -1,699,003 | -8,495,015 |
