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 41,785,427, 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 | 41,785,427 | |
| -1 | -41,785,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,785,427.
Example:
1 x 41,785,427 = 41,785,427
and
-1 x -41,785,427 = 41,785,427
Notice both answers equal 41,785,427
With that explanation out of the way, let's continue. Next, we take the number 41,785,427 and divide it by 2:
41,785,427 ÷ 2 = 20,892,713.5
If the quotient is a whole number, then 2 and 20,892,713.5 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 | 41,785,427 | |
| -1 | -41,785,427 |
Now, we try dividing 41,785,427 by 3:
41,785,427 ÷ 3 = 13,928,475.6667
If the quotient is a whole number, then 3 and 13,928,475.6667 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 | 41,785,427 | |
| -1 | -41,785,427 |
Let's try dividing by 4:
41,785,427 ÷ 4 = 10,446,356.75
If the quotient is a whole number, then 4 and 10,446,356.75 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 | 41,785,427 | |
| -1 | 41,785,427 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 61 | 589 | 1,159 | 1,163 | 1,891 | 22,097 | 35,929 | 36,053 | 70,943 | 685,007 | 1,347,917 | 2,199,233 | 41,785,427 |
| -1 | -19 | -31 | -61 | -589 | -1,159 | -1,163 | -1,891 | -22,097 | -35,929 | -36,053 | -70,943 | -685,007 | -1,347,917 | -2,199,233 | -41,785,427 |
