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 302,744,605, 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 | 302,744,605 | |
| -1 | -302,744,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,744,605.
Example:
1 x 302,744,605 = 302,744,605
and
-1 x -302,744,605 = 302,744,605
Notice both answers equal 302,744,605
With that explanation out of the way, let's continue. Next, we take the number 302,744,605 and divide it by 2:
302,744,605 ÷ 2 = 151,372,302.5
If the quotient is a whole number, then 2 and 151,372,302.5 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 | 302,744,605 | |
| -1 | -302,744,605 |
Now, we try dividing 302,744,605 by 3:
302,744,605 ÷ 3 = 100,914,868.3333
If the quotient is a whole number, then 3 and 100,914,868.3333 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 | 302,744,605 | |
| -1 | -302,744,605 |
Let's try dividing by 4:
302,744,605 ÷ 4 = 75,686,151.25
If the quotient is a whole number, then 4 and 75,686,151.25 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 | 302,744,605 | |
| -1 | 302,744,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 1,093 | 1,787 | 5,465 | 8,935 | 33,883 | 55,397 | 169,415 | 276,985 | 1,953,191 | 9,765,955 | 60,548,921 | 302,744,605 |
| -1 | -5 | -31 | -155 | -1,093 | -1,787 | -5,465 | -8,935 | -33,883 | -55,397 | -169,415 | -276,985 | -1,953,191 | -9,765,955 | -60,548,921 | -302,744,605 |
