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 37,836,085, 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 | 37,836,085 | |
| -1 | -37,836,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,836,085.
Example:
1 x 37,836,085 = 37,836,085
and
-1 x -37,836,085 = 37,836,085
Notice both answers equal 37,836,085
With that explanation out of the way, let's continue. Next, we take the number 37,836,085 and divide it by 2:
37,836,085 ÷ 2 = 18,918,042.5
If the quotient is a whole number, then 2 and 18,918,042.5 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 | 37,836,085 | |
| -1 | -37,836,085 |
Now, we try dividing 37,836,085 by 3:
37,836,085 ÷ 3 = 12,612,028.3333
If the quotient is a whole number, then 3 and 12,612,028.3333 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 | 37,836,085 | |
| -1 | -37,836,085 |
Let's try dividing by 4:
37,836,085 ÷ 4 = 9,459,021.25
If the quotient is a whole number, then 4 and 9,459,021.25 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 | 37,836,085 | |
| -1 | 37,836,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 389 | 397 | 1,945 | 1,985 | 2,723 | 2,779 | 13,615 | 13,895 | 19,061 | 19,453 | 95,305 | 97,265 | 154,433 | 772,165 | 1,081,031 | 5,405,155 | 7,567,217 | 37,836,085 |
| -1 | -5 | -7 | -35 | -49 | -245 | -389 | -397 | -1,945 | -1,985 | -2,723 | -2,779 | -13,615 | -13,895 | -19,061 | -19,453 | -95,305 | -97,265 | -154,433 | -772,165 | -1,081,031 | -5,405,155 | -7,567,217 | -37,836,085 |
