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 150,666,545, 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 | 150,666,545 | |
| -1 | -150,666,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,666,545.
Example:
1 x 150,666,545 = 150,666,545
and
-1 x -150,666,545 = 150,666,545
Notice both answers equal 150,666,545
With that explanation out of the way, let's continue. Next, we take the number 150,666,545 and divide it by 2:
150,666,545 ÷ 2 = 75,333,272.5
If the quotient is a whole number, then 2 and 75,333,272.5 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 | 150,666,545 | |
| -1 | -150,666,545 |
Now, we try dividing 150,666,545 by 3:
150,666,545 ÷ 3 = 50,222,181.6667
If the quotient is a whole number, then 3 and 50,222,181.6667 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 | 150,666,545 | |
| -1 | -150,666,545 |
Let's try dividing by 4:
150,666,545 ÷ 4 = 37,666,636.25
If the quotient is a whole number, then 4 and 37,666,636.25 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 | 150,666,545 | |
| -1 | 150,666,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 265 | 509 | 1,117 | 2,545 | 5,585 | 26,977 | 59,201 | 134,885 | 296,005 | 568,553 | 2,842,765 | 30,133,309 | 150,666,545 |
| -1 | -5 | -53 | -265 | -509 | -1,117 | -2,545 | -5,585 | -26,977 | -59,201 | -134,885 | -296,005 | -568,553 | -2,842,765 | -30,133,309 | -150,666,545 |
