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 10,637,245, 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 | 10,637,245 | |
| -1 | -10,637,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,637,245.
Example:
1 x 10,637,245 = 10,637,245
and
-1 x -10,637,245 = 10,637,245
Notice both answers equal 10,637,245
With that explanation out of the way, let's continue. Next, we take the number 10,637,245 and divide it by 2:
10,637,245 ÷ 2 = 5,318,622.5
If the quotient is a whole number, then 2 and 5,318,622.5 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 | 10,637,245 | |
| -1 | -10,637,245 |
Now, we try dividing 10,637,245 by 3:
10,637,245 ÷ 3 = 3,545,748.3333
If the quotient is a whole number, then 3 and 3,545,748.3333 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 | 10,637,245 | |
| -1 | -10,637,245 |
Let's try dividing by 4:
10,637,245 ÷ 4 = 2,659,311.25
If the quotient is a whole number, then 4 and 2,659,311.25 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 | 10,637,245 | |
| -1 | 10,637,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 41 | 95 | 205 | 779 | 2,731 | 3,895 | 13,655 | 51,889 | 111,971 | 259,445 | 559,855 | 2,127,449 | 10,637,245 |
| -1 | -5 | -19 | -41 | -95 | -205 | -779 | -2,731 | -3,895 | -13,655 | -51,889 | -111,971 | -259,445 | -559,855 | -2,127,449 | -10,637,245 |
