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 41,422,415, 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 | 41,422,415 | |
| -1 | -41,422,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,422,415.
Example:
1 x 41,422,415 = 41,422,415
and
-1 x -41,422,415 = 41,422,415
Notice both answers equal 41,422,415
With that explanation out of the way, let's continue. Next, we take the number 41,422,415 and divide it by 2:
41,422,415 ÷ 2 = 20,711,207.5
If the quotient is a whole number, then 2 and 20,711,207.5 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 | 41,422,415 | |
| -1 | -41,422,415 |
Now, we try dividing 41,422,415 by 3:
41,422,415 ÷ 3 = 13,807,471.6667
If the quotient is a whole number, then 3 and 13,807,471.6667 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 | 41,422,415 | |
| -1 | -41,422,415 |
Let's try dividing by 4:
41,422,415 ÷ 4 = 10,355,603.75
If the quotient is a whole number, then 4 and 10,355,603.75 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 | 41,422,415 | |
| -1 | 41,422,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 67 | 265 | 335 | 2,333 | 3,551 | 11,665 | 17,755 | 123,649 | 156,311 | 618,245 | 781,555 | 8,284,483 | 41,422,415 |
| -1 | -5 | -53 | -67 | -265 | -335 | -2,333 | -3,551 | -11,665 | -17,755 | -123,649 | -156,311 | -618,245 | -781,555 | -8,284,483 | -41,422,415 |
