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 8,551,195, 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 | 8,551,195 | |
| -1 | -8,551,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,551,195.
Example:
1 x 8,551,195 = 8,551,195
and
-1 x -8,551,195 = 8,551,195
Notice both answers equal 8,551,195
With that explanation out of the way, let's continue. Next, we take the number 8,551,195 and divide it by 2:
8,551,195 ÷ 2 = 4,275,597.5
If the quotient is a whole number, then 2 and 4,275,597.5 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 | 8,551,195 | |
| -1 | -8,551,195 |
Now, we try dividing 8,551,195 by 3:
8,551,195 ÷ 3 = 2,850,398.3333
If the quotient is a whole number, then 3 and 2,850,398.3333 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 | 8,551,195 | |
| -1 | -8,551,195 |
Let's try dividing by 4:
8,551,195 ÷ 4 = 2,137,798.75
If the quotient is a whole number, then 4 and 2,137,798.75 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 | 8,551,195 | |
| -1 | 8,551,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 43 | 155 | 215 | 1,283 | 1,333 | 6,415 | 6,665 | 39,773 | 55,169 | 198,865 | 275,845 | 1,710,239 | 8,551,195 |
| -1 | -5 | -31 | -43 | -155 | -215 | -1,283 | -1,333 | -6,415 | -6,665 | -39,773 | -55,169 | -198,865 | -275,845 | -1,710,239 | -8,551,195 |
