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 7,173,565, 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 | 7,173,565 | |
| -1 | -7,173,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,173,565.
Example:
1 x 7,173,565 = 7,173,565
and
-1 x -7,173,565 = 7,173,565
Notice both answers equal 7,173,565
With that explanation out of the way, let's continue. Next, we take the number 7,173,565 and divide it by 2:
7,173,565 ÷ 2 = 3,586,782.5
If the quotient is a whole number, then 2 and 3,586,782.5 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 | 7,173,565 | |
| -1 | -7,173,565 |
Now, we try dividing 7,173,565 by 3:
7,173,565 ÷ 3 = 2,391,188.3333
If the quotient is a whole number, then 3 and 2,391,188.3333 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 | 7,173,565 | |
| -1 | -7,173,565 |
Let's try dividing by 4:
7,173,565 ÷ 4 = 1,793,391.25
If the quotient is a whole number, then 4 and 1,793,391.25 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 | 7,173,565 | |
| -1 | 7,173,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 205 | 287 | 1,435 | 4,999 | 24,995 | 34,993 | 174,965 | 204,959 | 1,024,795 | 1,434,713 | 7,173,565 |
| -1 | -5 | -7 | -35 | -41 | -205 | -287 | -1,435 | -4,999 | -24,995 | -34,993 | -174,965 | -204,959 | -1,024,795 | -1,434,713 | -7,173,565 |
