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 37,087,015, 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 | 37,087,015 | |
| -1 | -37,087,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,087,015.
Example:
1 x 37,087,015 = 37,087,015
and
-1 x -37,087,015 = 37,087,015
Notice both answers equal 37,087,015
With that explanation out of the way, let's continue. Next, we take the number 37,087,015 and divide it by 2:
37,087,015 ÷ 2 = 18,543,507.5
If the quotient is a whole number, then 2 and 18,543,507.5 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 | 37,087,015 | |
| -1 | -37,087,015 |
Now, we try dividing 37,087,015 by 3:
37,087,015 ÷ 3 = 12,362,338.3333
If the quotient is a whole number, then 3 and 12,362,338.3333 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 | 37,087,015 | |
| -1 | -37,087,015 |
Let's try dividing by 4:
37,087,015 ÷ 4 = 9,271,753.75
If the quotient is a whole number, then 4 and 9,271,753.75 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 | 37,087,015 | |
| -1 | 37,087,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 | 19,993 | 99,965 | 139,951 | 699,755 | 1,059,629 | 5,298,145 | 7,417,403 | 37,087,015 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 | -19,993 | -99,965 | -139,951 | -699,755 | -1,059,629 | -5,298,145 | -7,417,403 | -37,087,015 |
