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 43,042,505, 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 | 43,042,505 | |
| -1 | -43,042,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,042,505.
Example:
1 x 43,042,505 = 43,042,505
and
-1 x -43,042,505 = 43,042,505
Notice both answers equal 43,042,505
With that explanation out of the way, let's continue. Next, we take the number 43,042,505 and divide it by 2:
43,042,505 ÷ 2 = 21,521,252.5
If the quotient is a whole number, then 2 and 21,521,252.5 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 | 43,042,505 | |
| -1 | -43,042,505 |
Now, we try dividing 43,042,505 by 3:
43,042,505 ÷ 3 = 14,347,501.6667
If the quotient is a whole number, then 3 and 14,347,501.6667 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 | 43,042,505 | |
| -1 | -43,042,505 |
Let's try dividing by 4:
43,042,505 ÷ 4 = 10,760,626.25
If the quotient is a whole number, then 4 and 10,760,626.25 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 | 43,042,505 | |
| -1 | 43,042,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 41,189 | 205,945 | 453,079 | 782,591 | 2,265,395 | 3,912,955 | 8,608,501 | 43,042,505 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -41,189 | -205,945 | -453,079 | -782,591 | -2,265,395 | -3,912,955 | -8,608,501 | -43,042,505 |
