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 41,120,485, 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 | 41,120,485 | |
| -1 | -41,120,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,120,485.
Example:
1 x 41,120,485 = 41,120,485
and
-1 x -41,120,485 = 41,120,485
Notice both answers equal 41,120,485
With that explanation out of the way, let's continue. Next, we take the number 41,120,485 and divide it by 2:
41,120,485 ÷ 2 = 20,560,242.5
If the quotient is a whole number, then 2 and 20,560,242.5 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 | 41,120,485 | |
| -1 | -41,120,485 |
Now, we try dividing 41,120,485 by 3:
41,120,485 ÷ 3 = 13,706,828.3333
If the quotient is a whole number, then 3 and 13,706,828.3333 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 | 41,120,485 | |
| -1 | -41,120,485 |
Let's try dividing by 4:
41,120,485 ÷ 4 = 10,280,121.25
If the quotient is a whole number, then 4 and 10,280,121.25 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 | 41,120,485 | |
| -1 | 41,120,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 181 | 905 | 1,267 | 6,335 | 6,491 | 32,455 | 45,437 | 227,185 | 1,174,871 | 5,874,355 | 8,224,097 | 41,120,485 |
| -1 | -5 | -7 | -35 | -181 | -905 | -1,267 | -6,335 | -6,491 | -32,455 | -45,437 | -227,185 | -1,174,871 | -5,874,355 | -8,224,097 | -41,120,485 |
