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 43,810,507, 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 | 43,810,507 | |
| -1 | -43,810,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,810,507.
Example:
1 x 43,810,507 = 43,810,507
and
-1 x -43,810,507 = 43,810,507
Notice both answers equal 43,810,507
With that explanation out of the way, let's continue. Next, we take the number 43,810,507 and divide it by 2:
43,810,507 ÷ 2 = 21,905,253.5
If the quotient is a whole number, then 2 and 21,905,253.5 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 | 43,810,507 | |
| -1 | -43,810,507 |
Now, we try dividing 43,810,507 by 3:
43,810,507 ÷ 3 = 14,603,502.3333
If the quotient is a whole number, then 3 and 14,603,502.3333 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 | 43,810,507 | |
| -1 | -43,810,507 |
Let's try dividing by 4:
43,810,507 ÷ 4 = 10,952,626.75
If the quotient is a whole number, then 4 and 10,952,626.75 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 | 43,810,507 | |
| -1 | 43,810,507 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 181 | 433 | 559 | 2,353 | 5,629 | 7,783 | 18,619 | 78,373 | 101,179 | 242,047 | 1,018,849 | 3,370,039 | 43,810,507 |
| -1 | -13 | -43 | -181 | -433 | -559 | -2,353 | -5,629 | -7,783 | -18,619 | -78,373 | -101,179 | -242,047 | -1,018,849 | -3,370,039 | -43,810,507 |
