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 245,334,235, 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 | 245,334,235 | |
| -1 | -245,334,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,334,235.
Example:
1 x 245,334,235 = 245,334,235
and
-1 x -245,334,235 = 245,334,235
Notice both answers equal 245,334,235
With that explanation out of the way, let's continue. Next, we take the number 245,334,235 and divide it by 2:
245,334,235 ÷ 2 = 122,667,117.5
If the quotient is a whole number, then 2 and 122,667,117.5 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 | 245,334,235 | |
| -1 | -245,334,235 |
Now, we try dividing 245,334,235 by 3:
245,334,235 ÷ 3 = 81,778,078.3333
If the quotient is a whole number, then 3 and 81,778,078.3333 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 | 245,334,235 | |
| -1 | -245,334,235 |
Let's try dividing by 4:
245,334,235 ÷ 4 = 61,333,558.75
If the quotient is a whole number, then 4 and 61,333,558.75 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 | 245,334,235 | |
| -1 | 245,334,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 67 | 185 | 335 | 2,479 | 12,395 | 19,793 | 98,965 | 732,341 | 1,326,131 | 3,661,705 | 6,630,655 | 49,066,847 | 245,334,235 |
| -1 | -5 | -37 | -67 | -185 | -335 | -2,479 | -12,395 | -19,793 | -98,965 | -732,341 | -1,326,131 | -3,661,705 | -6,630,655 | -49,066,847 | -245,334,235 |
