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 152,505,065, 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 | 152,505,065 | |
| -1 | -152,505,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,505,065.
Example:
1 x 152,505,065 = 152,505,065
and
-1 x -152,505,065 = 152,505,065
Notice both answers equal 152,505,065
With that explanation out of the way, let's continue. Next, we take the number 152,505,065 and divide it by 2:
152,505,065 ÷ 2 = 76,252,532.5
If the quotient is a whole number, then 2 and 76,252,532.5 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 | 152,505,065 | |
| -1 | -152,505,065 |
Now, we try dividing 152,505,065 by 3:
152,505,065 ÷ 3 = 50,835,021.6667
If the quotient is a whole number, then 3 and 50,835,021.6667 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 | 152,505,065 | |
| -1 | -152,505,065 |
Let's try dividing by 4:
152,505,065 ÷ 4 = 38,126,266.25
If the quotient is a whole number, then 4 and 38,126,266.25 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 | 152,505,065 | |
| -1 | 152,505,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 67 | 115 | 335 | 1,541 | 7,705 | 19,793 | 98,965 | 455,239 | 1,326,131 | 2,276,195 | 6,630,655 | 30,501,013 | 152,505,065 |
| -1 | -5 | -23 | -67 | -115 | -335 | -1,541 | -7,705 | -19,793 | -98,965 | -455,239 | -1,326,131 | -2,276,195 | -6,630,655 | -30,501,013 | -152,505,065 |
