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 9,657,115, 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 | 9,657,115 | |
| -1 | -9,657,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,657,115.
Example:
1 x 9,657,115 = 9,657,115
and
-1 x -9,657,115 = 9,657,115
Notice both answers equal 9,657,115
With that explanation out of the way, let's continue. Next, we take the number 9,657,115 and divide it by 2:
9,657,115 ÷ 2 = 4,828,557.5
If the quotient is a whole number, then 2 and 4,828,557.5 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 | 9,657,115 | |
| -1 | -9,657,115 |
Now, we try dividing 9,657,115 by 3:
9,657,115 ÷ 3 = 3,219,038.3333
If the quotient is a whole number, then 3 and 3,219,038.3333 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 | 9,657,115 | |
| -1 | -9,657,115 |
Let's try dividing by 4:
9,657,115 ÷ 4 = 2,414,278.75
If the quotient is a whole number, then 4 and 2,414,278.75 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 | 9,657,115 | |
| -1 | 9,657,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 101 | 505 | 1,313 | 1,471 | 6,565 | 7,355 | 19,123 | 95,615 | 148,571 | 742,855 | 1,931,423 | 9,657,115 |
| -1 | -5 | -13 | -65 | -101 | -505 | -1,313 | -1,471 | -6,565 | -7,355 | -19,123 | -95,615 | -148,571 | -742,855 | -1,931,423 | -9,657,115 |
