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 235,764,571, 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 | 235,764,571 | |
| -1 | -235,764,571 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,764,571.
Example:
1 x 235,764,571 = 235,764,571
and
-1 x -235,764,571 = 235,764,571
Notice both answers equal 235,764,571
With that explanation out of the way, let's continue. Next, we take the number 235,764,571 and divide it by 2:
235,764,571 ÷ 2 = 117,882,285.5
If the quotient is a whole number, then 2 and 117,882,285.5 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 | 235,764,571 | |
| -1 | -235,764,571 |
Now, we try dividing 235,764,571 by 3:
235,764,571 ÷ 3 = 78,588,190.3333
If the quotient is a whole number, then 3 and 78,588,190.3333 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 | 235,764,571 | |
| -1 | -235,764,571 |
Let's try dividing by 4:
235,764,571 ÷ 4 = 58,941,142.75
If the quotient is a whole number, then 4 and 58,941,142.75 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 | 235,764,571 | |
| -1 | 235,764,571 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 83 | 301 | 581 | 3,569 | 9,437 | 24,983 | 66,059 | 405,791 | 783,271 | 2,840,537 | 5,482,897 | 33,680,653 | 235,764,571 |
| -1 | -7 | -43 | -83 | -301 | -581 | -3,569 | -9,437 | -24,983 | -66,059 | -405,791 | -783,271 | -2,840,537 | -5,482,897 | -33,680,653 | -235,764,571 |
