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 41,951,845, 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 | 41,951,845 | |
| -1 | -41,951,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,951,845.
Example:
1 x 41,951,845 = 41,951,845
and
-1 x -41,951,845 = 41,951,845
Notice both answers equal 41,951,845
With that explanation out of the way, let's continue. Next, we take the number 41,951,845 and divide it by 2:
41,951,845 ÷ 2 = 20,975,922.5
If the quotient is a whole number, then 2 and 20,975,922.5 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 | 41,951,845 | |
| -1 | -41,951,845 |
Now, we try dividing 41,951,845 by 3:
41,951,845 ÷ 3 = 13,983,948.3333
If the quotient is a whole number, then 3 and 13,983,948.3333 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 | 41,951,845 | |
| -1 | -41,951,845 |
Let's try dividing by 4:
41,951,845 ÷ 4 = 10,487,961.25
If the quotient is a whole number, then 4 and 10,487,961.25 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 | 41,951,845 | |
| -1 | 41,951,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 541 | 1,193 | 2,705 | 5,965 | 7,033 | 15,509 | 35,165 | 77,545 | 645,413 | 3,227,065 | 8,390,369 | 41,951,845 |
| -1 | -5 | -13 | -65 | -541 | -1,193 | -2,705 | -5,965 | -7,033 | -15,509 | -35,165 | -77,545 | -645,413 | -3,227,065 | -8,390,369 | -41,951,845 |
