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 45,585,785, 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 | 45,585,785 | |
| -1 | -45,585,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,585,785.
Example:
1 x 45,585,785 = 45,585,785
and
-1 x -45,585,785 = 45,585,785
Notice both answers equal 45,585,785
With that explanation out of the way, let's continue. Next, we take the number 45,585,785 and divide it by 2:
45,585,785 ÷ 2 = 22,792,892.5
If the quotient is a whole number, then 2 and 22,792,892.5 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 | 45,585,785 | |
| -1 | -45,585,785 |
Now, we try dividing 45,585,785 by 3:
45,585,785 ÷ 3 = 15,195,261.6667
If the quotient is a whole number, then 3 and 15,195,261.6667 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 | 45,585,785 | |
| -1 | -45,585,785 |
Let's try dividing by 4:
45,585,785 ÷ 4 = 11,396,446.25
If the quotient is a whole number, then 4 and 11,396,446.25 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 | 45,585,785 | |
| -1 | 45,585,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 571 | 2,281 | 2,855 | 3,997 | 11,405 | 15,967 | 19,985 | 79,835 | 1,302,451 | 6,512,255 | 9,117,157 | 45,585,785 |
| -1 | -5 | -7 | -35 | -571 | -2,281 | -2,855 | -3,997 | -11,405 | -15,967 | -19,985 | -79,835 | -1,302,451 | -6,512,255 | -9,117,157 | -45,585,785 |
