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 10,300,277, 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 | 10,300,277 | |
| -1 | -10,300,277 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,300,277.
Example:
1 x 10,300,277 = 10,300,277
and
-1 x -10,300,277 = 10,300,277
Notice both answers equal 10,300,277
With that explanation out of the way, let's continue. Next, we take the number 10,300,277 and divide it by 2:
10,300,277 ÷ 2 = 5,150,138.5
If the quotient is a whole number, then 2 and 5,150,138.5 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 | 10,300,277 | |
| -1 | -10,300,277 |
Now, we try dividing 10,300,277 by 3:
10,300,277 ÷ 3 = 3,433,425.6667
If the quotient is a whole number, then 3 and 3,433,425.6667 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 | 10,300,277 | |
| -1 | -10,300,277 |
Let's try dividing by 4:
10,300,277 ÷ 4 = 2,575,069.25
If the quotient is a whole number, then 4 and 2,575,069.25 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 | 10,300,277 | |
| -1 | 10,300,277 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 61 | 403 | 419 | 793 | 1,891 | 5,447 | 12,989 | 24,583 | 25,559 | 168,857 | 332,267 | 792,329 | 10,300,277 |
| -1 | -13 | -31 | -61 | -403 | -419 | -793 | -1,891 | -5,447 | -12,989 | -24,583 | -25,559 | -168,857 | -332,267 | -792,329 | -10,300,277 |
