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 71,263,255, 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 | 71,263,255 | |
| -1 | -71,263,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,263,255.
Example:
1 x 71,263,255 = 71,263,255
and
-1 x -71,263,255 = 71,263,255
Notice both answers equal 71,263,255
With that explanation out of the way, let's continue. Next, we take the number 71,263,255 and divide it by 2:
71,263,255 ÷ 2 = 35,631,627.5
If the quotient is a whole number, then 2 and 35,631,627.5 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 | 71,263,255 | |
| -1 | -71,263,255 |
Now, we try dividing 71,263,255 by 3:
71,263,255 ÷ 3 = 23,754,418.3333
If the quotient is a whole number, then 3 and 23,754,418.3333 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 | 71,263,255 | |
| -1 | -71,263,255 |
Let's try dividing by 4:
71,263,255 ÷ 4 = 17,815,813.75
If the quotient is a whole number, then 4 and 17,815,813.75 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 | 71,263,255 | |
| -1 | 71,263,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 47,351 | 236,755 | 331,457 | 1,657,285 | 2,036,093 | 10,180,465 | 14,252,651 | 71,263,255 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -47,351 | -236,755 | -331,457 | -1,657,285 | -2,036,093 | -10,180,465 | -14,252,651 | -71,263,255 |
