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 88,747,271, 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 | 88,747,271 | |
| -1 | -88,747,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,747,271.
Example:
1 x 88,747,271 = 88,747,271
and
-1 x -88,747,271 = 88,747,271
Notice both answers equal 88,747,271
With that explanation out of the way, let's continue. Next, we take the number 88,747,271 and divide it by 2:
88,747,271 ÷ 2 = 44,373,635.5
If the quotient is a whole number, then 2 and 44,373,635.5 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 | 88,747,271 | |
| -1 | -88,747,271 |
Now, we try dividing 88,747,271 by 3:
88,747,271 ÷ 3 = 29,582,423.6667
If the quotient is a whole number, then 3 and 29,582,423.6667 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 | 88,747,271 | |
| -1 | -88,747,271 |
Let's try dividing by 4:
88,747,271 ÷ 4 = 22,186,817.75
If the quotient is a whole number, then 4 and 22,186,817.75 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 | 88,747,271 | |
| -1 | 88,747,271 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 311 | 437 | 653 | 5,909 | 7,153 | 12,407 | 15,019 | 135,907 | 203,083 | 285,361 | 3,858,577 | 4,670,909 | 88,747,271 |
| -1 | -19 | -23 | -311 | -437 | -653 | -5,909 | -7,153 | -12,407 | -15,019 | -135,907 | -203,083 | -285,361 | -3,858,577 | -4,670,909 | -88,747,271 |
