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 415,155,433, 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 | 415,155,433 | |
| -1 | -415,155,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 415,155,433.
Example:
1 x 415,155,433 = 415,155,433
and
-1 x -415,155,433 = 415,155,433
Notice both answers equal 415,155,433
With that explanation out of the way, let's continue. Next, we take the number 415,155,433 and divide it by 2:
415,155,433 ÷ 2 = 207,577,716.5
If the quotient is a whole number, then 2 and 207,577,716.5 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 | 415,155,433 | |
| -1 | -415,155,433 |
Now, we try dividing 415,155,433 by 3:
415,155,433 ÷ 3 = 138,385,144.3333
If the quotient is a whole number, then 3 and 138,385,144.3333 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 | 415,155,433 | |
| -1 | -415,155,433 |
Let's try dividing by 4:
415,155,433 ÷ 4 = 103,788,858.25
If the quotient is a whole number, then 4 and 103,788,858.25 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 | 415,155,433 | |
| -1 | 415,155,433 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,297 | 4,157 | 9,079 | 14,267 | 29,099 | 45,727 | 99,869 | 320,089 | 5,391,629 | 37,741,403 | 59,307,919 | 415,155,433 |
| -1 | -7 | -11 | -77 | -1,297 | -4,157 | -9,079 | -14,267 | -29,099 | -45,727 | -99,869 | -320,089 | -5,391,629 | -37,741,403 | -59,307,919 | -415,155,433 |
