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 157,116,595, 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 | 157,116,595 | |
| -1 | -157,116,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 157,116,595.
Example:
1 x 157,116,595 = 157,116,595
and
-1 x -157,116,595 = 157,116,595
Notice both answers equal 157,116,595
With that explanation out of the way, let's continue. Next, we take the number 157,116,595 and divide it by 2:
157,116,595 ÷ 2 = 78,558,297.5
If the quotient is a whole number, then 2 and 78,558,297.5 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 | 157,116,595 | |
| -1 | -157,116,595 |
Now, we try dividing 157,116,595 by 3:
157,116,595 ÷ 3 = 52,372,198.3333
If the quotient is a whole number, then 3 and 52,372,198.3333 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 | 157,116,595 | |
| -1 | -157,116,595 |
Let's try dividing by 4:
157,116,595 ÷ 4 = 39,279,148.75
If the quotient is a whole number, then 4 and 39,279,148.75 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 | 157,116,595 | |
| -1 | 157,116,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 443 | 445 | 797 | 2,215 | 3,985 | 39,427 | 70,933 | 197,135 | 353,071 | 354,665 | 1,765,355 | 31,423,319 | 157,116,595 |
| -1 | -5 | -89 | -443 | -445 | -797 | -2,215 | -3,985 | -39,427 | -70,933 | -197,135 | -353,071 | -354,665 | -1,765,355 | -31,423,319 | -157,116,595 |
