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 40,546,745, 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 | 40,546,745 | |
| -1 | -40,546,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,546,745.
Example:
1 x 40,546,745 = 40,546,745
and
-1 x -40,546,745 = 40,546,745
Notice both answers equal 40,546,745
With that explanation out of the way, let's continue. Next, we take the number 40,546,745 and divide it by 2:
40,546,745 ÷ 2 = 20,273,372.5
If the quotient is a whole number, then 2 and 20,273,372.5 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 | 40,546,745 | |
| -1 | -40,546,745 |
Now, we try dividing 40,546,745 by 3:
40,546,745 ÷ 3 = 13,515,581.6667
If the quotient is a whole number, then 3 and 13,515,581.6667 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 | 40,546,745 | |
| -1 | -40,546,745 |
Let's try dividing by 4:
40,546,745 ÷ 4 = 10,136,686.25
If the quotient is a whole number, then 4 and 10,136,686.25 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 | 40,546,745 | |
| -1 | 40,546,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 83 | 205 | 415 | 2,383 | 3,403 | 11,915 | 17,015 | 97,703 | 197,789 | 488,515 | 988,945 | 8,109,349 | 40,546,745 |
| -1 | -5 | -41 | -83 | -205 | -415 | -2,383 | -3,403 | -11,915 | -17,015 | -97,703 | -197,789 | -488,515 | -988,945 | -8,109,349 | -40,546,745 |
