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 43,015,027, 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 | 43,015,027 | |
| -1 | -43,015,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,015,027.
Example:
1 x 43,015,027 = 43,015,027
and
-1 x -43,015,027 = 43,015,027
Notice both answers equal 43,015,027
With that explanation out of the way, let's continue. Next, we take the number 43,015,027 and divide it by 2:
43,015,027 ÷ 2 = 21,507,513.5
If the quotient is a whole number, then 2 and 21,507,513.5 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 | 43,015,027 | |
| -1 | -43,015,027 |
Now, we try dividing 43,015,027 by 3:
43,015,027 ÷ 3 = 14,338,342.3333
If the quotient is a whole number, then 3 and 14,338,342.3333 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 | 43,015,027 | |
| -1 | -43,015,027 |
Let's try dividing by 4:
43,015,027 ÷ 4 = 10,753,756.75
If the quotient is a whole number, then 4 and 10,753,756.75 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 | 43,015,027 | |
| -1 | 43,015,027 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 127 | 451 | 751 | 1,397 | 5,207 | 8,261 | 30,791 | 57,277 | 95,377 | 338,701 | 1,049,147 | 3,910,457 | 43,015,027 |
| -1 | -11 | -41 | -127 | -451 | -751 | -1,397 | -5,207 | -8,261 | -30,791 | -57,277 | -95,377 | -338,701 | -1,049,147 | -3,910,457 | -43,015,027 |
