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 71,341,325, 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 | 71,341,325 | |
| -1 | -71,341,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,341,325.
Example:
1 x 71,341,325 = 71,341,325
and
-1 x -71,341,325 = 71,341,325
Notice both answers equal 71,341,325
With that explanation out of the way, let's continue. Next, we take the number 71,341,325 and divide it by 2:
71,341,325 ÷ 2 = 35,670,662.5
If the quotient is a whole number, then 2 and 35,670,662.5 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 | 71,341,325 | |
| -1 | -71,341,325 |
Now, we try dividing 71,341,325 by 3:
71,341,325 ÷ 3 = 23,780,441.6667
If the quotient is a whole number, then 3 and 23,780,441.6667 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 | 71,341,325 | |
| -1 | -71,341,325 |
Let's try dividing by 4:
71,341,325 ÷ 4 = 17,835,331.25
If the quotient is a whole number, then 4 and 17,835,331.25 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 | 71,341,325 | |
| -1 | 71,341,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 59 | 275 | 295 | 649 | 1,475 | 3,245 | 4,397 | 16,225 | 21,985 | 48,367 | 109,925 | 241,835 | 259,423 | 1,209,175 | 1,297,115 | 2,853,653 | 6,485,575 | 14,268,265 | 71,341,325 |
| -1 | -5 | -11 | -25 | -55 | -59 | -275 | -295 | -649 | -1,475 | -3,245 | -4,397 | -16,225 | -21,985 | -48,367 | -109,925 | -241,835 | -259,423 | -1,209,175 | -1,297,115 | -2,853,653 | -6,485,575 | -14,268,265 | -71,341,325 |
