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 61,414,105, 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 | 61,414,105 | |
| -1 | -61,414,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,414,105.
Example:
1 x 61,414,105 = 61,414,105
and
-1 x -61,414,105 = 61,414,105
Notice both answers equal 61,414,105
With that explanation out of the way, let's continue. Next, we take the number 61,414,105 and divide it by 2:
61,414,105 ÷ 2 = 30,707,052.5
If the quotient is a whole number, then 2 and 30,707,052.5 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 | 61,414,105 | |
| -1 | -61,414,105 |
Now, we try dividing 61,414,105 by 3:
61,414,105 ÷ 3 = 20,471,368.3333
If the quotient is a whole number, then 3 and 20,471,368.3333 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 | 61,414,105 | |
| -1 | -61,414,105 |
Let's try dividing by 4:
61,414,105 ÷ 4 = 15,353,526.25
If the quotient is a whole number, then 4 and 15,353,526.25 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 | 61,414,105 | |
| -1 | 61,414,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 43 | 205 | 215 | 1,763 | 6,967 | 8,815 | 34,835 | 285,647 | 299,581 | 1,428,235 | 1,497,905 | 12,282,821 | 61,414,105 |
| -1 | -5 | -41 | -43 | -205 | -215 | -1,763 | -6,967 | -8,815 | -34,835 | -285,647 | -299,581 | -1,428,235 | -1,497,905 | -12,282,821 | -61,414,105 |
