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 41,142,205, 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 | 41,142,205 | |
| -1 | -41,142,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,142,205.
Example:
1 x 41,142,205 = 41,142,205
and
-1 x -41,142,205 = 41,142,205
Notice both answers equal 41,142,205
With that explanation out of the way, let's continue. Next, we take the number 41,142,205 and divide it by 2:
41,142,205 ÷ 2 = 20,571,102.5
If the quotient is a whole number, then 2 and 20,571,102.5 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 | 41,142,205 | |
| -1 | -41,142,205 |
Now, we try dividing 41,142,205 by 3:
41,142,205 ÷ 3 = 13,714,068.3333
If the quotient is a whole number, then 3 and 13,714,068.3333 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 | 41,142,205 | |
| -1 | -41,142,205 |
Let's try dividing by 4:
41,142,205 ÷ 4 = 10,285,551.25
If the quotient is a whole number, then 4 and 10,285,551.25 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 | 41,142,205 | |
| -1 | 41,142,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 169 | 181 | 269 | 845 | 905 | 1,345 | 2,353 | 3,497 | 11,765 | 17,485 | 30,589 | 45,461 | 48,689 | 152,945 | 227,305 | 243,445 | 632,957 | 3,164,785 | 8,228,441 | 41,142,205 |
| -1 | -5 | -13 | -65 | -169 | -181 | -269 | -845 | -905 | -1,345 | -2,353 | -3,497 | -11,765 | -17,485 | -30,589 | -45,461 | -48,689 | -152,945 | -227,305 | -243,445 | -632,957 | -3,164,785 | -8,228,441 | -41,142,205 |
