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 478,136,035, 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 | 478,136,035 | |
| -1 | -478,136,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 478,136,035.
Example:
1 x 478,136,035 = 478,136,035
and
-1 x -478,136,035 = 478,136,035
Notice both answers equal 478,136,035
With that explanation out of the way, let's continue. Next, we take the number 478,136,035 and divide it by 2:
478,136,035 ÷ 2 = 239,068,017.5
If the quotient is a whole number, then 2 and 239,068,017.5 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 | 478,136,035 | |
| -1 | -478,136,035 |
Now, we try dividing 478,136,035 by 3:
478,136,035 ÷ 3 = 159,378,678.3333
If the quotient is a whole number, then 3 and 159,378,678.3333 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 | 478,136,035 | |
| -1 | -478,136,035 |
Let's try dividing by 4:
478,136,035 ÷ 4 = 119,534,008.75
If the quotient is a whole number, then 4 and 119,534,008.75 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 | 478,136,035 | |
| -1 | 478,136,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 89 | 445 | 1,157 | 5,785 | 82,651 | 413,255 | 1,074,463 | 5,372,315 | 7,355,939 | 36,779,695 | 95,627,207 | 478,136,035 |
| -1 | -5 | -13 | -65 | -89 | -445 | -1,157 | -5,785 | -82,651 | -413,255 | -1,074,463 | -5,372,315 | -7,355,939 | -36,779,695 | -95,627,207 | -478,136,035 |
