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 302,032,325, 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 | 302,032,325 | |
| -1 | -302,032,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,032,325.
Example:
1 x 302,032,325 = 302,032,325
and
-1 x -302,032,325 = 302,032,325
Notice both answers equal 302,032,325
With that explanation out of the way, let's continue. Next, we take the number 302,032,325 and divide it by 2:
302,032,325 ÷ 2 = 151,016,162.5
If the quotient is a whole number, then 2 and 151,016,162.5 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 | 302,032,325 | |
| -1 | -302,032,325 |
Now, we try dividing 302,032,325 by 3:
302,032,325 ÷ 3 = 100,677,441.6667
If the quotient is a whole number, then 3 and 100,677,441.6667 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 | 302,032,325 | |
| -1 | -302,032,325 |
Let's try dividing by 4:
302,032,325 ÷ 4 = 75,508,081.25
If the quotient is a whole number, then 4 and 75,508,081.25 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 | 302,032,325 | |
| -1 | 302,032,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 246,557 | 1,232,785 | 1,725,899 | 6,163,925 | 8,629,495 | 12,081,293 | 43,147,475 | 60,406,465 | 302,032,325 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -246,557 | -1,232,785 | -1,725,899 | -6,163,925 | -8,629,495 | -12,081,293 | -43,147,475 | -60,406,465 | -302,032,325 |
