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 324,635,773, 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 | 324,635,773 | |
| -1 | -324,635,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,635,773.
Example:
1 x 324,635,773 = 324,635,773
and
-1 x -324,635,773 = 324,635,773
Notice both answers equal 324,635,773
With that explanation out of the way, let's continue. Next, we take the number 324,635,773 and divide it by 2:
324,635,773 ÷ 2 = 162,317,886.5
If the quotient is a whole number, then 2 and 162,317,886.5 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 | 324,635,773 | |
| -1 | -324,635,773 |
Now, we try dividing 324,635,773 by 3:
324,635,773 ÷ 3 = 108,211,924.3333
If the quotient is a whole number, then 3 and 108,211,924.3333 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 | 324,635,773 | |
| -1 | -324,635,773 |
Let's try dividing by 4:
324,635,773 ÷ 4 = 81,158,943.25
If the quotient is a whole number, then 4 and 81,158,943.25 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 | 324,635,773 | |
| -1 | 324,635,773 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 77 | 203 | 319 | 2,233 | 145,381 | 1,017,667 | 1,599,191 | 4,216,049 | 11,194,337 | 29,512,343 | 46,376,539 | 324,635,773 |
| -1 | -7 | -11 | -29 | -77 | -203 | -319 | -2,233 | -145,381 | -1,017,667 | -1,599,191 | -4,216,049 | -11,194,337 | -29,512,343 | -46,376,539 | -324,635,773 |
