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 37,677,665, 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 | 37,677,665 | |
| -1 | -37,677,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,677,665.
Example:
1 x 37,677,665 = 37,677,665
and
-1 x -37,677,665 = 37,677,665
Notice both answers equal 37,677,665
With that explanation out of the way, let's continue. Next, we take the number 37,677,665 and divide it by 2:
37,677,665 ÷ 2 = 18,838,832.5
If the quotient is a whole number, then 2 and 18,838,832.5 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 | 37,677,665 | |
| -1 | -37,677,665 |
Now, we try dividing 37,677,665 by 3:
37,677,665 ÷ 3 = 12,559,221.6667
If the quotient is a whole number, then 3 and 12,559,221.6667 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 | 37,677,665 | |
| -1 | -37,677,665 |
Let's try dividing by 4:
37,677,665 ÷ 4 = 9,419,416.25
If the quotient is a whole number, then 4 and 9,419,416.25 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 | 37,677,665 | |
| -1 | 37,677,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 199 | 995 | 1,993 | 3,781 | 9,965 | 18,905 | 37,867 | 189,335 | 396,607 | 1,983,035 | 7,535,533 | 37,677,665 |
| -1 | -5 | -19 | -95 | -199 | -995 | -1,993 | -3,781 | -9,965 | -18,905 | -37,867 | -189,335 | -396,607 | -1,983,035 | -7,535,533 | -37,677,665 |
