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 10,051,255, 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 | 10,051,255 | |
| -1 | -10,051,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,051,255.
Example:
1 x 10,051,255 = 10,051,255
and
-1 x -10,051,255 = 10,051,255
Notice both answers equal 10,051,255
With that explanation out of the way, let's continue. Next, we take the number 10,051,255 and divide it by 2:
10,051,255 ÷ 2 = 5,025,627.5
If the quotient is a whole number, then 2 and 5,025,627.5 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 | 10,051,255 | |
| -1 | -10,051,255 |
Now, we try dividing 10,051,255 by 3:
10,051,255 ÷ 3 = 3,350,418.3333
If the quotient is a whole number, then 3 and 3,350,418.3333 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 | 10,051,255 | |
| -1 | -10,051,255 |
Let's try dividing by 4:
10,051,255 ÷ 4 = 2,512,813.75
If the quotient is a whole number, then 4 and 2,512,813.75 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 | 10,051,255 | |
| -1 | 10,051,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 103 | 145 | 515 | 673 | 2,987 | 3,365 | 14,935 | 19,517 | 69,319 | 97,585 | 346,595 | 2,010,251 | 10,051,255 |
| -1 | -5 | -29 | -103 | -145 | -515 | -673 | -2,987 | -3,365 | -14,935 | -19,517 | -69,319 | -97,585 | -346,595 | -2,010,251 | -10,051,255 |
