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 335,325,263, 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 | 335,325,263 | |
| -1 | -335,325,263 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 335,325,263.
Example:
1 x 335,325,263 = 335,325,263
and
-1 x -335,325,263 = 335,325,263
Notice both answers equal 335,325,263
With that explanation out of the way, let's continue. Next, we take the number 335,325,263 and divide it by 2:
335,325,263 ÷ 2 = 167,662,631.5
If the quotient is a whole number, then 2 and 167,662,631.5 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 | 335,325,263 | |
| -1 | -335,325,263 |
Now, we try dividing 335,325,263 by 3:
335,325,263 ÷ 3 = 111,775,087.6667
If the quotient is a whole number, then 3 and 111,775,087.6667 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 | 335,325,263 | |
| -1 | -335,325,263 |
Let's try dividing by 4:
335,325,263 ÷ 4 = 83,831,315.75
If the quotient is a whole number, then 4 and 83,831,315.75 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 | 335,325,263 | |
| -1 | 335,325,263 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 263 | 1,841 | 3,419 | 14,011 | 23,933 | 98,077 | 182,143 | 1,275,001 | 3,684,893 | 25,794,251 | 47,903,609 | 335,325,263 |
| -1 | -7 | -13 | -91 | -263 | -1,841 | -3,419 | -14,011 | -23,933 | -98,077 | -182,143 | -1,275,001 | -3,684,893 | -25,794,251 | -47,903,609 | -335,325,263 |
