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 61,941,935, 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 | 61,941,935 | |
| -1 | -61,941,935 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,941,935.
Example:
1 x 61,941,935 = 61,941,935
and
-1 x -61,941,935 = 61,941,935
Notice both answers equal 61,941,935
With that explanation out of the way, let's continue. Next, we take the number 61,941,935 and divide it by 2:
61,941,935 ÷ 2 = 30,970,967.5
If the quotient is a whole number, then 2 and 30,970,967.5 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 | 61,941,935 | |
| -1 | -61,941,935 |
Now, we try dividing 61,941,935 by 3:
61,941,935 ÷ 3 = 20,647,311.6667
If the quotient is a whole number, then 3 and 20,647,311.6667 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 | 61,941,935 | |
| -1 | -61,941,935 |
Let's try dividing by 4:
61,941,935 ÷ 4 = 15,485,483.75
If the quotient is a whole number, then 4 and 15,485,483.75 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 | 61,941,935 | |
| -1 | 61,941,935 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 503 | 2,239 | 2,515 | 5,533 | 11,195 | 24,629 | 27,665 | 123,145 | 1,126,217 | 5,631,085 | 12,388,387 | 61,941,935 |
| -1 | -5 | -11 | -55 | -503 | -2,239 | -2,515 | -5,533 | -11,195 | -24,629 | -27,665 | -123,145 | -1,126,217 | -5,631,085 | -12,388,387 | -61,941,935 |
