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 71,158,757, 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 | 71,158,757 | |
| -1 | -71,158,757 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,158,757.
Example:
1 x 71,158,757 = 71,158,757
and
-1 x -71,158,757 = 71,158,757
Notice both answers equal 71,158,757
With that explanation out of the way, let's continue. Next, we take the number 71,158,757 and divide it by 2:
71,158,757 ÷ 2 = 35,579,378.5
If the quotient is a whole number, then 2 and 35,579,378.5 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 | 71,158,757 | |
| -1 | -71,158,757 |
Now, we try dividing 71,158,757 by 3:
71,158,757 ÷ 3 = 23,719,585.6667
If the quotient is a whole number, then 3 and 23,719,585.6667 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 | 71,158,757 | |
| -1 | -71,158,757 |
Let's try dividing by 4:
71,158,757 ÷ 4 = 17,789,689.25
If the quotient is a whole number, then 4 and 17,789,689.25 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 | 71,158,757 | |
| -1 | 71,158,757 |
If you did it right, you will end up with this table:
| 1 | 23 | 61 | 67 | 757 | 1,403 | 1,541 | 4,087 | 17,411 | 46,177 | 50,719 | 94,001 | 1,062,071 | 1,166,537 | 3,093,859 | 71,158,757 |
| -1 | -23 | -61 | -67 | -757 | -1,403 | -1,541 | -4,087 | -17,411 | -46,177 | -50,719 | -94,001 | -1,062,071 | -1,166,537 | -3,093,859 | -71,158,757 |
