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 5,131,027, 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 | 5,131,027 | |
| -1 | -5,131,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,131,027.
Example:
1 x 5,131,027 = 5,131,027
and
-1 x -5,131,027 = 5,131,027
Notice both answers equal 5,131,027
With that explanation out of the way, let's continue. Next, we take the number 5,131,027 and divide it by 2:
5,131,027 ÷ 2 = 2,565,513.5
If the quotient is a whole number, then 2 and 2,565,513.5 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 | 5,131,027 | |
| -1 | -5,131,027 |
Now, we try dividing 5,131,027 by 3:
5,131,027 ÷ 3 = 1,710,342.3333
If the quotient is a whole number, then 3 and 1,710,342.3333 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 | 5,131,027 | |
| -1 | -5,131,027 |
Let's try dividing by 4:
5,131,027 ÷ 4 = 1,282,756.75
If the quotient is a whole number, then 4 and 1,282,756.75 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 | 5,131,027 | |
| -1 | 5,131,027 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 41 | 341 | 367 | 451 | 1,271 | 4,037 | 11,377 | 13,981 | 15,047 | 125,147 | 165,517 | 466,457 | 5,131,027 |
| -1 | -11 | -31 | -41 | -341 | -367 | -451 | -1,271 | -4,037 | -11,377 | -13,981 | -15,047 | -125,147 | -165,517 | -466,457 | -5,131,027 |
