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 345,240,523, 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 | 345,240,523 | |
| -1 | -345,240,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,240,523.
Example:
1 x 345,240,523 = 345,240,523
and
-1 x -345,240,523 = 345,240,523
Notice both answers equal 345,240,523
With that explanation out of the way, let's continue. Next, we take the number 345,240,523 and divide it by 2:
345,240,523 ÷ 2 = 172,620,261.5
If the quotient is a whole number, then 2 and 172,620,261.5 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 | 345,240,523 | |
| -1 | -345,240,523 |
Now, we try dividing 345,240,523 by 3:
345,240,523 ÷ 3 = 115,080,174.3333
If the quotient is a whole number, then 3 and 115,080,174.3333 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 | 345,240,523 | |
| -1 | -345,240,523 |
Let's try dividing by 4:
345,240,523 ÷ 4 = 86,310,130.75
If the quotient is a whole number, then 4 and 86,310,130.75 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 | 345,240,523 | |
| -1 | 345,240,523 |
If you did it right, you will end up with this table:
| 1 | 89 | 101 | 193 | 199 | 8,989 | 17,177 | 17,711 | 19,493 | 20,099 | 38,407 | 1,734,877 | 1,788,811 | 3,418,223 | 3,879,107 | 345,240,523 |
| -1 | -89 | -101 | -193 | -199 | -8,989 | -17,177 | -17,711 | -19,493 | -20,099 | -38,407 | -1,734,877 | -1,788,811 | -3,418,223 | -3,879,107 | -345,240,523 |
