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 302,010,761, 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 | 302,010,761 | |
| -1 | -302,010,761 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,010,761.
Example:
1 x 302,010,761 = 302,010,761
and
-1 x -302,010,761 = 302,010,761
Notice both answers equal 302,010,761
With that explanation out of the way, let's continue. Next, we take the number 302,010,761 and divide it by 2:
302,010,761 ÷ 2 = 151,005,380.5
If the quotient is a whole number, then 2 and 151,005,380.5 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 | 302,010,761 | |
| -1 | -302,010,761 |
Now, we try dividing 302,010,761 by 3:
302,010,761 ÷ 3 = 100,670,253.6667
If the quotient is a whole number, then 3 and 100,670,253.6667 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 | 302,010,761 | |
| -1 | -302,010,761 |
Let's try dividing by 4:
302,010,761 ÷ 4 = 75,502,690.25
If the quotient is a whole number, then 4 and 75,502,690.25 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 | 302,010,761 | |
| -1 | 302,010,761 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 97 | 481 | 1,261 | 3,589 | 6,473 | 46,657 | 84,149 | 239,501 | 627,881 | 3,113,513 | 8,162,453 | 23,231,597 | 302,010,761 |
| -1 | -13 | -37 | -97 | -481 | -1,261 | -3,589 | -6,473 | -46,657 | -84,149 | -239,501 | -627,881 | -3,113,513 | -8,162,453 | -23,231,597 | -302,010,761 |
