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 41,425,415, 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 | 41,425,415 | |
| -1 | -41,425,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,425,415.
Example:
1 x 41,425,415 = 41,425,415
and
-1 x -41,425,415 = 41,425,415
Notice both answers equal 41,425,415
With that explanation out of the way, let's continue. Next, we take the number 41,425,415 and divide it by 2:
41,425,415 ÷ 2 = 20,712,707.5
If the quotient is a whole number, then 2 and 20,712,707.5 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 | 41,425,415 | |
| -1 | -41,425,415 |
Now, we try dividing 41,425,415 by 3:
41,425,415 ÷ 3 = 13,808,471.6667
If the quotient is a whole number, then 3 and 13,808,471.6667 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 | 41,425,415 | |
| -1 | -41,425,415 |
Let's try dividing by 4:
41,425,415 ÷ 4 = 10,356,353.75
If the quotient is a whole number, then 4 and 10,356,353.75 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 | 41,425,415 | |
| -1 | 41,425,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 2,185 | 18,959 | 94,795 | 360,221 | 436,057 | 1,801,105 | 2,180,285 | 8,285,083 | 41,425,415 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -2,185 | -18,959 | -94,795 | -360,221 | -436,057 | -1,801,105 | -2,180,285 | -8,285,083 | -41,425,415 |
