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 302,615,203, 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 | 302,615,203 | |
| -1 | -302,615,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,615,203.
Example:
1 x 302,615,203 = 302,615,203
and
-1 x -302,615,203 = 302,615,203
Notice both answers equal 302,615,203
With that explanation out of the way, let's continue. Next, we take the number 302,615,203 and divide it by 2:
302,615,203 ÷ 2 = 151,307,601.5
If the quotient is a whole number, then 2 and 151,307,601.5 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 | 302,615,203 | |
| -1 | -302,615,203 |
Now, we try dividing 302,615,203 by 3:
302,615,203 ÷ 3 = 100,871,734.3333
If the quotient is a whole number, then 3 and 100,871,734.3333 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 | 302,615,203 | |
| -1 | -302,615,203 |
Let's try dividing by 4:
302,615,203 ÷ 4 = 75,653,800.75
If the quotient is a whole number, then 4 and 75,653,800.75 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 | 302,615,203 | |
| -1 | 302,615,203 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 319 | 379 | 2,503 | 4,169 | 10,991 | 27,533 | 72,587 | 120,901 | 798,457 | 948,637 | 10,435,007 | 27,510,473 | 302,615,203 |
| -1 | -11 | -29 | -319 | -379 | -2,503 | -4,169 | -10,991 | -27,533 | -72,587 | -120,901 | -798,457 | -948,637 | -10,435,007 | -27,510,473 | -302,615,203 |
