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 37,309,883, 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 | 37,309,883 | |
| -1 | -37,309,883 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,309,883.
Example:
1 x 37,309,883 = 37,309,883
and
-1 x -37,309,883 = 37,309,883
Notice both answers equal 37,309,883
With that explanation out of the way, let's continue. Next, we take the number 37,309,883 and divide it by 2:
37,309,883 ÷ 2 = 18,654,941.5
If the quotient is a whole number, then 2 and 18,654,941.5 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 | 37,309,883 | |
| -1 | -37,309,883 |
Now, we try dividing 37,309,883 by 3:
37,309,883 ÷ 3 = 12,436,627.6667
If the quotient is a whole number, then 3 and 12,436,627.6667 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 | 37,309,883 | |
| -1 | -37,309,883 |
Let's try dividing by 4:
37,309,883 ÷ 4 = 9,327,470.75
If the quotient is a whole number, then 4 and 9,327,470.75 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 | 37,309,883 | |
| -1 | 37,309,883 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 79 | 221 | 1,027 | 1,343 | 2,137 | 17,459 | 27,781 | 36,329 | 168,823 | 472,277 | 2,194,699 | 2,869,991 | 37,309,883 |
| -1 | -13 | -17 | -79 | -221 | -1,027 | -1,343 | -2,137 | -17,459 | -27,781 | -36,329 | -168,823 | -472,277 | -2,194,699 | -2,869,991 | -37,309,883 |
