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 10,262,305, 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 | 10,262,305 | |
| -1 | -10,262,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,262,305.
Example:
1 x 10,262,305 = 10,262,305
and
-1 x -10,262,305 = 10,262,305
Notice both answers equal 10,262,305
With that explanation out of the way, let's continue. Next, we take the number 10,262,305 and divide it by 2:
10,262,305 ÷ 2 = 5,131,152.5
If the quotient is a whole number, then 2 and 5,131,152.5 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 | 10,262,305 | |
| -1 | -10,262,305 |
Now, we try dividing 10,262,305 by 3:
10,262,305 ÷ 3 = 3,420,768.3333
If the quotient is a whole number, then 3 and 3,420,768.3333 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 | 10,262,305 | |
| -1 | -10,262,305 |
Let's try dividing by 4:
10,262,305 ÷ 4 = 2,565,576.25
If the quotient is a whole number, then 4 and 2,565,576.25 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 | 10,262,305 | |
| -1 | 10,262,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 157 | 769 | 785 | 2,669 | 3,845 | 13,073 | 13,345 | 65,365 | 120,733 | 603,665 | 2,052,461 | 10,262,305 |
| -1 | -5 | -17 | -85 | -157 | -769 | -785 | -2,669 | -3,845 | -13,073 | -13,345 | -65,365 | -120,733 | -603,665 | -2,052,461 | -10,262,305 |
