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 302,010,769, 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 | 302,010,769 | |
| -1 | -302,010,769 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,010,769.
Example:
1 x 302,010,769 = 302,010,769
and
-1 x -302,010,769 = 302,010,769
Notice both answers equal 302,010,769
With that explanation out of the way, let's continue. Next, we take the number 302,010,769 and divide it by 2:
302,010,769 ÷ 2 = 151,005,384.5
If the quotient is a whole number, then 2 and 151,005,384.5 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 | 302,010,769 | |
| -1 | -302,010,769 |
Now, we try dividing 302,010,769 by 3:
302,010,769 ÷ 3 = 100,670,256.3333
If the quotient is a whole number, then 3 and 100,670,256.3333 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 | 302,010,769 | |
| -1 | -302,010,769 |
Let's try dividing by 4:
302,010,769 ÷ 4 = 75,502,692.25
If the quotient is a whole number, then 4 and 75,502,692.25 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 | 302,010,769 | |
| -1 | 302,010,769 |
If you did it right, you will end up with this table:
| 1 | 23 | 109 | 179 | 673 | 2,507 | 4,117 | 15,479 | 19,511 | 73,357 | 120,467 | 448,753 | 1,687,211 | 2,770,741 | 13,130,903 | 302,010,769 |
| -1 | -23 | -109 | -179 | -673 | -2,507 | -4,117 | -15,479 | -19,511 | -73,357 | -120,467 | -448,753 | -1,687,211 | -2,770,741 | -13,130,903 | -302,010,769 |
