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 152,354,323, 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 | 152,354,323 | |
| -1 | -152,354,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,354,323.
Example:
1 x 152,354,323 = 152,354,323
and
-1 x -152,354,323 = 152,354,323
Notice both answers equal 152,354,323
With that explanation out of the way, let's continue. Next, we take the number 152,354,323 and divide it by 2:
152,354,323 ÷ 2 = 76,177,161.5
If the quotient is a whole number, then 2 and 76,177,161.5 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 | 152,354,323 | |
| -1 | -152,354,323 |
Now, we try dividing 152,354,323 by 3:
152,354,323 ÷ 3 = 50,784,774.3333
If the quotient is a whole number, then 3 and 50,784,774.3333 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 | 152,354,323 | |
| -1 | -152,354,323 |
Let's try dividing by 4:
152,354,323 ÷ 4 = 38,088,580.75
If the quotient is a whole number, then 4 and 38,088,580.75 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 | 152,354,323 | |
| -1 | 152,354,323 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 23 | 187 | 253 | 391 | 4,301 | 35,423 | 389,653 | 602,191 | 814,729 | 6,624,101 | 8,962,019 | 13,850,393 | 152,354,323 |
| -1 | -11 | -17 | -23 | -187 | -253 | -391 | -4,301 | -35,423 | -389,653 | -602,191 | -814,729 | -6,624,101 | -8,962,019 | -13,850,393 | -152,354,323 |
