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 147,395,065, 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 | 147,395,065 | |
| -1 | -147,395,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,395,065.
Example:
1 x 147,395,065 = 147,395,065
and
-1 x -147,395,065 = 147,395,065
Notice both answers equal 147,395,065
With that explanation out of the way, let's continue. Next, we take the number 147,395,065 and divide it by 2:
147,395,065 ÷ 2 = 73,697,532.5
If the quotient is a whole number, then 2 and 73,697,532.5 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 | 147,395,065 | |
| -1 | -147,395,065 |
Now, we try dividing 147,395,065 by 3:
147,395,065 ÷ 3 = 49,131,688.3333
If the quotient is a whole number, then 3 and 49,131,688.3333 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 | 147,395,065 | |
| -1 | -147,395,065 |
Let's try dividing by 4:
147,395,065 ÷ 4 = 36,848,766.25
If the quotient is a whole number, then 4 and 36,848,766.25 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 | 147,395,065 | |
| -1 | 147,395,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 193 | 965 | 3,667 | 8,039 | 18,335 | 40,195 | 152,741 | 763,705 | 1,551,527 | 7,757,635 | 29,479,013 | 147,395,065 |
| -1 | -5 | -19 | -95 | -193 | -965 | -3,667 | -8,039 | -18,335 | -40,195 | -152,741 | -763,705 | -1,551,527 | -7,757,635 | -29,479,013 | -147,395,065 |
