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 731,171,771, 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 | 731,171,771 | |
| -1 | -731,171,771 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 731,171,771.
Example:
1 x 731,171,771 = 731,171,771
and
-1 x -731,171,771 = 731,171,771
Notice both answers equal 731,171,771
With that explanation out of the way, let's continue. Next, we take the number 731,171,771 and divide it by 2:
731,171,771 ÷ 2 = 365,585,885.5
If the quotient is a whole number, then 2 and 365,585,885.5 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 | 731,171,771 | |
| -1 | -731,171,771 |
Now, we try dividing 731,171,771 by 3:
731,171,771 ÷ 3 = 243,723,923.6667
If the quotient is a whole number, then 3 and 243,723,923.6667 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 | 731,171,771 | |
| -1 | -731,171,771 |
Let's try dividing by 4:
731,171,771 ÷ 4 = 182,792,942.75
If the quotient is a whole number, then 4 and 182,792,942.75 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 | 731,171,771 | |
| -1 | 731,171,771 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 253 | 401 | 4,411 | 7,207 | 9,223 | 79,277 | 101,453 | 165,761 | 1,823,371 | 2,890,007 | 31,790,077 | 66,470,161 | 731,171,771 |
| -1 | -11 | -23 | -253 | -401 | -4,411 | -7,207 | -9,223 | -79,277 | -101,453 | -165,761 | -1,823,371 | -2,890,007 | -31,790,077 | -66,470,161 | -731,171,771 |
