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 10,117,555, 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 | 10,117,555 | |
| -1 | -10,117,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,117,555.
Example:
1 x 10,117,555 = 10,117,555
and
-1 x -10,117,555 = 10,117,555
Notice both answers equal 10,117,555
With that explanation out of the way, let's continue. Next, we take the number 10,117,555 and divide it by 2:
10,117,555 ÷ 2 = 5,058,777.5
If the quotient is a whole number, then 2 and 5,058,777.5 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 | 10,117,555 | |
| -1 | -10,117,555 |
Now, we try dividing 10,117,555 by 3:
10,117,555 ÷ 3 = 3,372,518.3333
If the quotient is a whole number, then 3 and 3,372,518.3333 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 | 10,117,555 | |
| -1 | -10,117,555 |
Let's try dividing by 4:
10,117,555 ÷ 4 = 2,529,388.75
If the quotient is a whole number, then 4 and 2,529,388.75 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 | 10,117,555 | |
| -1 | 10,117,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 467 | 619 | 2,335 | 3,095 | 3,269 | 4,333 | 16,345 | 21,665 | 289,073 | 1,445,365 | 2,023,511 | 10,117,555 |
| -1 | -5 | -7 | -35 | -467 | -619 | -2,335 | -3,095 | -3,269 | -4,333 | -16,345 | -21,665 | -289,073 | -1,445,365 | -2,023,511 | -10,117,555 |
