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 152,605,045, 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 | 152,605,045 | |
| -1 | -152,605,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,605,045.
Example:
1 x 152,605,045 = 152,605,045
and
-1 x -152,605,045 = 152,605,045
Notice both answers equal 152,605,045
With that explanation out of the way, let's continue. Next, we take the number 152,605,045 and divide it by 2:
152,605,045 ÷ 2 = 76,302,522.5
If the quotient is a whole number, then 2 and 76,302,522.5 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 | 152,605,045 | |
| -1 | -152,605,045 |
Now, we try dividing 152,605,045 by 3:
152,605,045 ÷ 3 = 50,868,348.3333
If the quotient is a whole number, then 3 and 50,868,348.3333 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 | 152,605,045 | |
| -1 | -152,605,045 |
Let's try dividing by 4:
152,605,045 ÷ 4 = 38,151,261.25
If the quotient is a whole number, then 4 and 38,151,261.25 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 | 152,605,045 | |
| -1 | 152,605,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 269 | 415 | 1,345 | 1,367 | 6,835 | 22,327 | 111,635 | 113,461 | 367,723 | 567,305 | 1,838,615 | 30,521,009 | 152,605,045 |
| -1 | -5 | -83 | -269 | -415 | -1,345 | -1,367 | -6,835 | -22,327 | -111,635 | -113,461 | -367,723 | -567,305 | -1,838,615 | -30,521,009 | -152,605,045 |
