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 10,027,555, 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 | 10,027,555 | |
| -1 | -10,027,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,027,555.
Example:
1 x 10,027,555 = 10,027,555
and
-1 x -10,027,555 = 10,027,555
Notice both answers equal 10,027,555
With that explanation out of the way, let's continue. Next, we take the number 10,027,555 and divide it by 2:
10,027,555 ÷ 2 = 5,013,777.5
If the quotient is a whole number, then 2 and 5,013,777.5 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 | 10,027,555 | |
| -1 | -10,027,555 |
Now, we try dividing 10,027,555 by 3:
10,027,555 ÷ 3 = 3,342,518.3333
If the quotient is a whole number, then 3 and 3,342,518.3333 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 | 10,027,555 | |
| -1 | -10,027,555 |
Let's try dividing by 4:
10,027,555 ÷ 4 = 2,506,888.75
If the quotient is a whole number, then 4 and 2,506,888.75 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 | 10,027,555 | |
| -1 | 10,027,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 67 | 185 | 335 | 809 | 2,479 | 4,045 | 12,395 | 29,933 | 54,203 | 149,665 | 271,015 | 2,005,511 | 10,027,555 |
| -1 | -5 | -37 | -67 | -185 | -335 | -809 | -2,479 | -4,045 | -12,395 | -29,933 | -54,203 | -149,665 | -271,015 | -2,005,511 | -10,027,555 |
