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 37,706,647, 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 | 37,706,647 | |
| -1 | -37,706,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,706,647.
Example:
1 x 37,706,647 = 37,706,647
and
-1 x -37,706,647 = 37,706,647
Notice both answers equal 37,706,647
With that explanation out of the way, let's continue. Next, we take the number 37,706,647 and divide it by 2:
37,706,647 ÷ 2 = 18,853,323.5
If the quotient is a whole number, then 2 and 18,853,323.5 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 | 37,706,647 | |
| -1 | -37,706,647 |
Now, we try dividing 37,706,647 by 3:
37,706,647 ÷ 3 = 12,568,882.3333
If the quotient is a whole number, then 3 and 12,568,882.3333 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 | 37,706,647 | |
| -1 | -37,706,647 |
Let's try dividing by 4:
37,706,647 ÷ 4 = 9,426,661.75
If the quotient is a whole number, then 4 and 9,426,661.75 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 | 37,706,647 | |
| -1 | 37,706,647 |
If you did it right, you will end up with this table:
| 1 | 11 | 131 | 137 | 191 | 1,441 | 1,507 | 2,101 | 17,947 | 25,021 | 26,167 | 197,417 | 275,231 | 287,837 | 3,427,877 | 37,706,647 |
| -1 | -11 | -131 | -137 | -191 | -1,441 | -1,507 | -2,101 | -17,947 | -25,021 | -26,167 | -197,417 | -275,231 | -287,837 | -3,427,877 | -37,706,647 |
