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 8,505,449, 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 | 8,505,449 | |
| -1 | -8,505,449 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,505,449.
Example:
1 x 8,505,449 = 8,505,449
and
-1 x -8,505,449 = 8,505,449
Notice both answers equal 8,505,449
With that explanation out of the way, let's continue. Next, we take the number 8,505,449 and divide it by 2:
8,505,449 ÷ 2 = 4,252,724.5
If the quotient is a whole number, then 2 and 4,252,724.5 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 | 8,505,449 | |
| -1 | -8,505,449 |
Now, we try dividing 8,505,449 by 3:
8,505,449 ÷ 3 = 2,835,149.6667
If the quotient is a whole number, then 3 and 2,835,149.6667 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 | 8,505,449 | |
| -1 | -8,505,449 |
Let's try dividing by 4:
8,505,449 ÷ 4 = 2,126,362.25
If the quotient is a whole number, then 4 and 2,126,362.25 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 | 8,505,449 | |
| -1 | 8,505,449 |
If you did it right, you will end up with this table:
| 1 | 37 | 47 | 67 | 73 | 1,739 | 2,479 | 2,701 | 3,149 | 3,431 | 4,891 | 116,513 | 126,947 | 180,967 | 229,877 | 8,505,449 |
| -1 | -37 | -47 | -67 | -73 | -1,739 | -2,479 | -2,701 | -3,149 | -3,431 | -4,891 | -116,513 | -126,947 | -180,967 | -229,877 | -8,505,449 |
