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 71,601,035, 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 | 71,601,035 | |
| -1 | -71,601,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,601,035.
Example:
1 x 71,601,035 = 71,601,035
and
-1 x -71,601,035 = 71,601,035
Notice both answers equal 71,601,035
With that explanation out of the way, let's continue. Next, we take the number 71,601,035 and divide it by 2:
71,601,035 ÷ 2 = 35,800,517.5
If the quotient is a whole number, then 2 and 35,800,517.5 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 | 71,601,035 | |
| -1 | -71,601,035 |
Now, we try dividing 71,601,035 by 3:
71,601,035 ÷ 3 = 23,867,011.6667
If the quotient is a whole number, then 3 and 23,867,011.6667 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 | 71,601,035 | |
| -1 | -71,601,035 |
Let's try dividing by 4:
71,601,035 ÷ 4 = 17,900,258.75
If the quotient is a whole number, then 4 and 17,900,258.75 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 | 71,601,035 | |
| -1 | 71,601,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 97 | 485 | 1,067 | 5,335 | 13,421 | 67,105 | 147,631 | 738,155 | 1,301,837 | 6,509,185 | 14,320,207 | 71,601,035 |
| -1 | -5 | -11 | -55 | -97 | -485 | -1,067 | -5,335 | -13,421 | -67,105 | -147,631 | -738,155 | -1,301,837 | -6,509,185 | -14,320,207 | -71,601,035 |
