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 152,768,735, 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 | 152,768,735 | |
| -1 | -152,768,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,768,735.
Example:
1 x 152,768,735 = 152,768,735
and
-1 x -152,768,735 = 152,768,735
Notice both answers equal 152,768,735
With that explanation out of the way, let's continue. Next, we take the number 152,768,735 and divide it by 2:
152,768,735 ÷ 2 = 76,384,367.5
If the quotient is a whole number, then 2 and 76,384,367.5 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 | 152,768,735 | |
| -1 | -152,768,735 |
Now, we try dividing 152,768,735 by 3:
152,768,735 ÷ 3 = 50,922,911.6667
If the quotient is a whole number, then 3 and 50,922,911.6667 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 | 152,768,735 | |
| -1 | -152,768,735 |
Let's try dividing by 4:
152,768,735 ÷ 4 = 38,192,183.75
If the quotient is a whole number, then 4 and 38,192,183.75 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 | 152,768,735 | |
| -1 | 152,768,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 293 | 1,465 | 2,051 | 10,255 | 14,897 | 74,485 | 104,279 | 521,395 | 4,364,821 | 21,824,105 | 30,553,747 | 152,768,735 |
| -1 | -5 | -7 | -35 | -293 | -1,465 | -2,051 | -10,255 | -14,897 | -74,485 | -104,279 | -521,395 | -4,364,821 | -21,824,105 | -30,553,747 | -152,768,735 |
