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 71,544,755, 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 | 71,544,755 | |
| -1 | -71,544,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,544,755.
Example:
1 x 71,544,755 = 71,544,755
and
-1 x -71,544,755 = 71,544,755
Notice both answers equal 71,544,755
With that explanation out of the way, let's continue. Next, we take the number 71,544,755 and divide it by 2:
71,544,755 ÷ 2 = 35,772,377.5
If the quotient is a whole number, then 2 and 35,772,377.5 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 | 71,544,755 | |
| -1 | -71,544,755 |
Now, we try dividing 71,544,755 by 3:
71,544,755 ÷ 3 = 23,848,251.6667
If the quotient is a whole number, then 3 and 23,848,251.6667 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 | 71,544,755 | |
| -1 | -71,544,755 |
Let's try dividing by 4:
71,544,755 ÷ 4 = 17,886,188.75
If the quotient is a whole number, then 4 and 17,886,188.75 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 | 71,544,755 | |
| -1 | 71,544,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 83 | 85 | 415 | 1,411 | 7,055 | 10,141 | 50,705 | 172,397 | 841,703 | 861,985 | 4,208,515 | 14,308,951 | 71,544,755 |
| -1 | -5 | -17 | -83 | -85 | -415 | -1,411 | -7,055 | -10,141 | -50,705 | -172,397 | -841,703 | -861,985 | -4,208,515 | -14,308,951 | -71,544,755 |
