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 302,773,037, 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 | 302,773,037 | |
| -1 | -302,773,037 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,773,037.
Example:
1 x 302,773,037 = 302,773,037
and
-1 x -302,773,037 = 302,773,037
Notice both answers equal 302,773,037
With that explanation out of the way, let's continue. Next, we take the number 302,773,037 and divide it by 2:
302,773,037 ÷ 2 = 151,386,518.5
If the quotient is a whole number, then 2 and 151,386,518.5 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 | 302,773,037 | |
| -1 | -302,773,037 |
Now, we try dividing 302,773,037 by 3:
302,773,037 ÷ 3 = 100,924,345.6667
If the quotient is a whole number, then 3 and 100,924,345.6667 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 | 302,773,037 | |
| -1 | -302,773,037 |
Let's try dividing by 4:
302,773,037 ÷ 4 = 75,693,259.25
If the quotient is a whole number, then 4 and 75,693,259.25 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 | 302,773,037 | |
| -1 | 302,773,037 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 229 | 1,603 | 4,351 | 9,941 | 30,457 | 69,587 | 188,879 | 1,322,153 | 2,276,489 | 15,935,423 | 43,253,291 | 302,773,037 |
| -1 | -7 | -19 | -133 | -229 | -1,603 | -4,351 | -9,941 | -30,457 | -69,587 | -188,879 | -1,322,153 | -2,276,489 | -15,935,423 | -43,253,291 | -302,773,037 |
