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 485,528,435, 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 | 485,528,435 | |
| -1 | -485,528,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 485,528,435.
Example:
1 x 485,528,435 = 485,528,435
and
-1 x -485,528,435 = 485,528,435
Notice both answers equal 485,528,435
With that explanation out of the way, let's continue. Next, we take the number 485,528,435 and divide it by 2:
485,528,435 ÷ 2 = 242,764,217.5
If the quotient is a whole number, then 2 and 242,764,217.5 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 | 485,528,435 | |
| -1 | -485,528,435 |
Now, we try dividing 485,528,435 by 3:
485,528,435 ÷ 3 = 161,842,811.6667
If the quotient is a whole number, then 3 and 161,842,811.6667 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 | 485,528,435 | |
| -1 | -485,528,435 |
Let's try dividing by 4:
485,528,435 ÷ 4 = 121,382,108.75
If the quotient is a whole number, then 4 and 121,382,108.75 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 | 485,528,435 | |
| -1 | 485,528,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 599 | 2,995 | 4,193 | 20,965 | 23,159 | 115,795 | 162,113 | 810,565 | 13,872,241 | 69,361,205 | 97,105,687 | 485,528,435 |
| -1 | -5 | -7 | -35 | -599 | -2,995 | -4,193 | -20,965 | -23,159 | -115,795 | -162,113 | -810,565 | -13,872,241 | -69,361,205 | -97,105,687 | -485,528,435 |
