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 302,026,585, 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 | 302,026,585 | |
| -1 | -302,026,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,026,585.
Example:
1 x 302,026,585 = 302,026,585
and
-1 x -302,026,585 = 302,026,585
Notice both answers equal 302,026,585
With that explanation out of the way, let's continue. Next, we take the number 302,026,585 and divide it by 2:
302,026,585 ÷ 2 = 151,013,292.5
If the quotient is a whole number, then 2 and 151,013,292.5 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 | 302,026,585 | |
| -1 | -302,026,585 |
Now, we try dividing 302,026,585 by 3:
302,026,585 ÷ 3 = 100,675,528.3333
If the quotient is a whole number, then 3 and 100,675,528.3333 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 | 302,026,585 | |
| -1 | -302,026,585 |
Let's try dividing by 4:
302,026,585 ÷ 4 = 75,506,646.25
If the quotient is a whole number, then 4 and 75,506,646.25 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 | 302,026,585 | |
| -1 | 302,026,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 449 | 2,245 | 3,143 | 15,715 | 19,219 | 96,095 | 134,533 | 672,665 | 8,629,331 | 43,146,655 | 60,405,317 | 302,026,585 |
| -1 | -5 | -7 | -35 | -449 | -2,245 | -3,143 | -15,715 | -19,219 | -96,095 | -134,533 | -672,665 | -8,629,331 | -43,146,655 | -60,405,317 | -302,026,585 |
