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 43,804,745, 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 | 43,804,745 | |
| -1 | -43,804,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,804,745.
Example:
1 x 43,804,745 = 43,804,745
and
-1 x -43,804,745 = 43,804,745
Notice both answers equal 43,804,745
With that explanation out of the way, let's continue. Next, we take the number 43,804,745 and divide it by 2:
43,804,745 ÷ 2 = 21,902,372.5
If the quotient is a whole number, then 2 and 21,902,372.5 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 | 43,804,745 | |
| -1 | -43,804,745 |
Now, we try dividing 43,804,745 by 3:
43,804,745 ÷ 3 = 14,601,581.6667
If the quotient is a whole number, then 3 and 14,601,581.6667 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 | 43,804,745 | |
| -1 | -43,804,745 |
Let's try dividing by 4:
43,804,745 ÷ 4 = 10,951,186.25
If the quotient is a whole number, then 4 and 10,951,186.25 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 | 43,804,745 | |
| -1 | 43,804,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 73 | 215 | 365 | 2,791 | 3,139 | 13,955 | 15,695 | 120,013 | 203,743 | 600,065 | 1,018,715 | 8,760,949 | 43,804,745 |
| -1 | -5 | -43 | -73 | -215 | -365 | -2,791 | -3,139 | -13,955 | -15,695 | -120,013 | -203,743 | -600,065 | -1,018,715 | -8,760,949 | -43,804,745 |
