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 8,936,851, 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 | 8,936,851 | |
| -1 | -8,936,851 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,936,851.
Example:
1 x 8,936,851 = 8,936,851
and
-1 x -8,936,851 = 8,936,851
Notice both answers equal 8,936,851
With that explanation out of the way, let's continue. Next, we take the number 8,936,851 and divide it by 2:
8,936,851 ÷ 2 = 4,468,425.5
If the quotient is a whole number, then 2 and 4,468,425.5 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 | 8,936,851 | |
| -1 | -8,936,851 |
Now, we try dividing 8,936,851 by 3:
8,936,851 ÷ 3 = 2,978,950.3333
If the quotient is a whole number, then 3 and 2,978,950.3333 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 | 8,936,851 | |
| -1 | -8,936,851 |
Let's try dividing by 4:
8,936,851 ÷ 4 = 2,234,212.75
If the quotient is a whole number, then 4 and 2,234,212.75 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 | 8,936,851 | |
| -1 | 8,936,851 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 277 | 419 | 1,939 | 2,933 | 3,047 | 4,609 | 21,329 | 32,263 | 116,063 | 812,441 | 1,276,693 | 8,936,851 |
| -1 | -7 | -11 | -77 | -277 | -419 | -1,939 | -2,933 | -3,047 | -4,609 | -21,329 | -32,263 | -116,063 | -812,441 | -1,276,693 | -8,936,851 |
