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 152,666,005, 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 | 152,666,005 | |
| -1 | -152,666,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,666,005.
Example:
1 x 152,666,005 = 152,666,005
and
-1 x -152,666,005 = 152,666,005
Notice both answers equal 152,666,005
With that explanation out of the way, let's continue. Next, we take the number 152,666,005 and divide it by 2:
152,666,005 ÷ 2 = 76,333,002.5
If the quotient is a whole number, then 2 and 76,333,002.5 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 | 152,666,005 | |
| -1 | -152,666,005 |
Now, we try dividing 152,666,005 by 3:
152,666,005 ÷ 3 = 50,888,668.3333
If the quotient is a whole number, then 3 and 50,888,668.3333 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 | 152,666,005 | |
| -1 | -152,666,005 |
Let's try dividing by 4:
152,666,005 ÷ 4 = 38,166,501.25
If the quotient is a whole number, then 4 and 38,166,501.25 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 | 152,666,005 | |
| -1 | 152,666,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 887 | 1,187 | 4,435 | 5,935 | 25,723 | 34,423 | 128,615 | 172,115 | 1,052,869 | 5,264,345 | 30,533,201 | 152,666,005 |
| -1 | -5 | -29 | -145 | -887 | -1,187 | -4,435 | -5,935 | -25,723 | -34,423 | -128,615 | -172,115 | -1,052,869 | -5,264,345 | -30,533,201 | -152,666,005 |
