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 71,071,265, 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 | 71,071,265 | |
| -1 | -71,071,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,071,265.
Example:
1 x 71,071,265 = 71,071,265
and
-1 x -71,071,265 = 71,071,265
Notice both answers equal 71,071,265
With that explanation out of the way, let's continue. Next, we take the number 71,071,265 and divide it by 2:
71,071,265 ÷ 2 = 35,535,632.5
If the quotient is a whole number, then 2 and 35,535,632.5 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 | 71,071,265 | |
| -1 | -71,071,265 |
Now, we try dividing 71,071,265 by 3:
71,071,265 ÷ 3 = 23,690,421.6667
If the quotient is a whole number, then 3 and 23,690,421.6667 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 | 71,071,265 | |
| -1 | -71,071,265 |
Let's try dividing by 4:
71,071,265 ÷ 4 = 17,767,816.25
If the quotient is a whole number, then 4 and 17,767,816.25 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 | 71,071,265 | |
| -1 | 71,071,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 851 | 4,255 | 16,703 | 83,515 | 384,169 | 618,011 | 1,920,845 | 3,090,055 | 14,214,253 | 71,071,265 |
| -1 | -5 | -23 | -37 | -115 | -185 | -851 | -4,255 | -16,703 | -83,515 | -384,169 | -618,011 | -1,920,845 | -3,090,055 | -14,214,253 | -71,071,265 |
