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 71,685,295, 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 | 71,685,295 | |
| -1 | -71,685,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,685,295.
Example:
1 x 71,685,295 = 71,685,295
and
-1 x -71,685,295 = 71,685,295
Notice both answers equal 71,685,295
With that explanation out of the way, let's continue. Next, we take the number 71,685,295 and divide it by 2:
71,685,295 ÷ 2 = 35,842,647.5
If the quotient is a whole number, then 2 and 35,842,647.5 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 | 71,685,295 | |
| -1 | -71,685,295 |
Now, we try dividing 71,685,295 by 3:
71,685,295 ÷ 3 = 23,895,098.3333
If the quotient is a whole number, then 3 and 23,895,098.3333 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 | 71,685,295 | |
| -1 | -71,685,295 |
Let's try dividing by 4:
71,685,295 ÷ 4 = 17,921,323.75
If the quotient is a whole number, then 4 and 17,921,323.75 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 | 71,685,295 | |
| -1 | 71,685,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 59 | 295 | 649 | 3,245 | 22,091 | 110,455 | 243,001 | 1,215,005 | 1,303,369 | 6,516,845 | 14,337,059 | 71,685,295 |
| -1 | -5 | -11 | -55 | -59 | -295 | -649 | -3,245 | -22,091 | -110,455 | -243,001 | -1,215,005 | -1,303,369 | -6,516,845 | -14,337,059 | -71,685,295 |
