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 5,165,065, 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 | 5,165,065 | |
| -1 | -5,165,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,165,065.
Example:
1 x 5,165,065 = 5,165,065
and
-1 x -5,165,065 = 5,165,065
Notice both answers equal 5,165,065
With that explanation out of the way, let's continue. Next, we take the number 5,165,065 and divide it by 2:
5,165,065 ÷ 2 = 2,582,532.5
If the quotient is a whole number, then 2 and 2,582,532.5 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 | 5,165,065 | |
| -1 | -5,165,065 |
Now, we try dividing 5,165,065 by 3:
5,165,065 ÷ 3 = 1,721,688.3333
If the quotient is a whole number, then 3 and 1,721,688.3333 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 | 5,165,065 | |
| -1 | -5,165,065 |
Let's try dividing by 4:
5,165,065 ÷ 4 = 1,291,266.25
If the quotient is a whole number, then 4 and 1,291,266.25 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 | 5,165,065 | |
| -1 | 5,165,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 47 | 155 | 235 | 709 | 1,457 | 3,545 | 7,285 | 21,979 | 33,323 | 109,895 | 166,615 | 1,033,013 | 5,165,065 |
| -1 | -5 | -31 | -47 | -155 | -235 | -709 | -1,457 | -3,545 | -7,285 | -21,979 | -33,323 | -109,895 | -166,615 | -1,033,013 | -5,165,065 |
