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 45,540,565, 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 | 45,540,565 | |
| -1 | -45,540,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,540,565.
Example:
1 x 45,540,565 = 45,540,565
and
-1 x -45,540,565 = 45,540,565
Notice both answers equal 45,540,565
With that explanation out of the way, let's continue. Next, we take the number 45,540,565 and divide it by 2:
45,540,565 ÷ 2 = 22,770,282.5
If the quotient is a whole number, then 2 and 22,770,282.5 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 | 45,540,565 | |
| -1 | -45,540,565 |
Now, we try dividing 45,540,565 by 3:
45,540,565 ÷ 3 = 15,180,188.3333
If the quotient is a whole number, then 3 and 15,180,188.3333 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 | 45,540,565 | |
| -1 | -45,540,565 |
Let's try dividing by 4:
45,540,565 ÷ 4 = 11,385,141.25
If the quotient is a whole number, then 4 and 11,385,141.25 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 | 45,540,565 | |
| -1 | 45,540,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 241 | 1,205 | 1,687 | 5,399 | 8,435 | 26,995 | 37,793 | 188,965 | 1,301,159 | 6,505,795 | 9,108,113 | 45,540,565 |
| -1 | -5 | -7 | -35 | -241 | -1,205 | -1,687 | -5,399 | -8,435 | -26,995 | -37,793 | -188,965 | -1,301,159 | -6,505,795 | -9,108,113 | -45,540,565 |
