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 235,781,425, 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 | 235,781,425 | |
| -1 | -235,781,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,781,425.
Example:
1 x 235,781,425 = 235,781,425
and
-1 x -235,781,425 = 235,781,425
Notice both answers equal 235,781,425
With that explanation out of the way, let's continue. Next, we take the number 235,781,425 and divide it by 2:
235,781,425 ÷ 2 = 117,890,712.5
If the quotient is a whole number, then 2 and 117,890,712.5 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 | 235,781,425 | |
| -1 | -235,781,425 |
Now, we try dividing 235,781,425 by 3:
235,781,425 ÷ 3 = 78,593,808.3333
If the quotient is a whole number, then 3 and 78,593,808.3333 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 | 235,781,425 | |
| -1 | -235,781,425 |
Let's try dividing by 4:
235,781,425 ÷ 4 = 58,945,356.25
If the quotient is a whole number, then 4 and 58,945,356.25 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 | 235,781,425 | |
| -1 | 235,781,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 79 | 275 | 395 | 869 | 1,975 | 4,345 | 10,853 | 21,725 | 54,265 | 119,383 | 271,325 | 596,915 | 857,387 | 2,984,575 | 4,286,935 | 9,431,257 | 21,434,675 | 47,156,285 | 235,781,425 |
| -1 | -5 | -11 | -25 | -55 | -79 | -275 | -395 | -869 | -1,975 | -4,345 | -10,853 | -21,725 | -54,265 | -119,383 | -271,325 | -596,915 | -857,387 | -2,984,575 | -4,286,935 | -9,431,257 | -21,434,675 | -47,156,285 | -235,781,425 |
