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 10,078,835, 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 | 10,078,835 | |
| -1 | -10,078,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,078,835.
Example:
1 x 10,078,835 = 10,078,835
and
-1 x -10,078,835 = 10,078,835
Notice both answers equal 10,078,835
With that explanation out of the way, let's continue. Next, we take the number 10,078,835 and divide it by 2:
10,078,835 ÷ 2 = 5,039,417.5
If the quotient is a whole number, then 2 and 5,039,417.5 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 | 10,078,835 | |
| -1 | -10,078,835 |
Now, we try dividing 10,078,835 by 3:
10,078,835 ÷ 3 = 3,359,611.6667
If the quotient is a whole number, then 3 and 3,359,611.6667 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 | 10,078,835 | |
| -1 | -10,078,835 |
Let's try dividing by 4:
10,078,835 ÷ 4 = 2,519,708.75
If the quotient is a whole number, then 4 and 2,519,708.75 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 | 10,078,835 | |
| -1 | 10,078,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 8,161 | 40,805 | 106,093 | 155,059 | 530,465 | 775,295 | 2,015,767 | 10,078,835 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -8,161 | -40,805 | -106,093 | -155,059 | -530,465 | -775,295 | -2,015,767 | -10,078,835 |
