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 302,530,537, 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 | 302,530,537 | |
| -1 | -302,530,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,530,537.
Example:
1 x 302,530,537 = 302,530,537
and
-1 x -302,530,537 = 302,530,537
Notice both answers equal 302,530,537
With that explanation out of the way, let's continue. Next, we take the number 302,530,537 and divide it by 2:
302,530,537 ÷ 2 = 151,265,268.5
If the quotient is a whole number, then 2 and 151,265,268.5 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 | 302,530,537 | |
| -1 | -302,530,537 |
Now, we try dividing 302,530,537 by 3:
302,530,537 ÷ 3 = 100,843,512.3333
If the quotient is a whole number, then 3 and 100,843,512.3333 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 | 302,530,537 | |
| -1 | -302,530,537 |
Let's try dividing by 4:
302,530,537 ÷ 4 = 75,632,634.25
If the quotient is a whole number, then 4 and 75,632,634.25 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 | 302,530,537 | |
| -1 | 302,530,537 |
If you did it right, you will end up with this table:
| 1 | 37 | 61 | 311 | 431 | 2,257 | 11,507 | 15,947 | 18,971 | 26,291 | 134,041 | 701,927 | 972,767 | 4,959,517 | 8,176,501 | 302,530,537 |
| -1 | -37 | -61 | -311 | -431 | -2,257 | -11,507 | -15,947 | -18,971 | -26,291 | -134,041 | -701,927 | -972,767 | -4,959,517 | -8,176,501 | -302,530,537 |
