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 189,058,105, 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 | 189,058,105 | |
| -1 | -189,058,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 189,058,105.
Example:
1 x 189,058,105 = 189,058,105
and
-1 x -189,058,105 = 189,058,105
Notice both answers equal 189,058,105
With that explanation out of the way, let's continue. Next, we take the number 189,058,105 and divide it by 2:
189,058,105 ÷ 2 = 94,529,052.5
If the quotient is a whole number, then 2 and 94,529,052.5 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 | 189,058,105 | |
| -1 | -189,058,105 |
Now, we try dividing 189,058,105 by 3:
189,058,105 ÷ 3 = 63,019,368.3333
If the quotient is a whole number, then 3 and 63,019,368.3333 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 | 189,058,105 | |
| -1 | -189,058,105 |
Let's try dividing by 4:
189,058,105 ÷ 4 = 47,264,526.25
If the quotient is a whole number, then 4 and 47,264,526.25 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 | 189,058,105 | |
| -1 | 189,058,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 493 | 2,465 | 76,697 | 383,485 | 1,303,849 | 2,224,213 | 6,519,245 | 11,121,065 | 37,811,621 | 189,058,105 |
| -1 | -5 | -17 | -29 | -85 | -145 | -493 | -2,465 | -76,697 | -383,485 | -1,303,849 | -2,224,213 | -6,519,245 | -11,121,065 | -37,811,621 | -189,058,105 |
