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 45,753,745, 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 | 45,753,745 | |
| -1 | -45,753,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,753,745.
Example:
1 x 45,753,745 = 45,753,745
and
-1 x -45,753,745 = 45,753,745
Notice both answers equal 45,753,745
With that explanation out of the way, let's continue. Next, we take the number 45,753,745 and divide it by 2:
45,753,745 ÷ 2 = 22,876,872.5
If the quotient is a whole number, then 2 and 22,876,872.5 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 | 45,753,745 | |
| -1 | -45,753,745 |
Now, we try dividing 45,753,745 by 3:
45,753,745 ÷ 3 = 15,251,248.3333
If the quotient is a whole number, then 3 and 15,251,248.3333 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 | 45,753,745 | |
| -1 | -45,753,745 |
Let's try dividing by 4:
45,753,745 ÷ 4 = 11,438,436.25
If the quotient is a whole number, then 4 and 11,438,436.25 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 | 45,753,745 | |
| -1 | 45,753,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 307 | 727 | 1,535 | 3,635 | 12,587 | 29,807 | 62,935 | 149,035 | 223,189 | 1,115,945 | 9,150,749 | 45,753,745 |
| -1 | -5 | -41 | -205 | -307 | -727 | -1,535 | -3,635 | -12,587 | -29,807 | -62,935 | -149,035 | -223,189 | -1,115,945 | -9,150,749 | -45,753,745 |
