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 10,325,015, 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 | 10,325,015 | |
| -1 | -10,325,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,325,015.
Example:
1 x 10,325,015 = 10,325,015
and
-1 x -10,325,015 = 10,325,015
Notice both answers equal 10,325,015
With that explanation out of the way, let's continue. Next, we take the number 10,325,015 and divide it by 2:
10,325,015 ÷ 2 = 5,162,507.5
If the quotient is a whole number, then 2 and 5,162,507.5 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 | 10,325,015 | |
| -1 | -10,325,015 |
Now, we try dividing 10,325,015 by 3:
10,325,015 ÷ 3 = 3,441,671.6667
If the quotient is a whole number, then 3 and 3,441,671.6667 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 | 10,325,015 | |
| -1 | -10,325,015 |
Let's try dividing by 4:
10,325,015 ÷ 4 = 2,581,253.75
If the quotient is a whole number, then 4 and 2,581,253.75 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 | 10,325,015 | |
| -1 | 10,325,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 31 | 145 | 155 | 899 | 2,297 | 4,495 | 11,485 | 66,613 | 71,207 | 333,065 | 356,035 | 2,065,003 | 10,325,015 |
| -1 | -5 | -29 | -31 | -145 | -155 | -899 | -2,297 | -4,495 | -11,485 | -66,613 | -71,207 | -333,065 | -356,035 | -2,065,003 | -10,325,015 |
