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 150,354,127, 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 | 150,354,127 | |
| -1 | -150,354,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,354,127.
Example:
1 x 150,354,127 = 150,354,127
and
-1 x -150,354,127 = 150,354,127
Notice both answers equal 150,354,127
With that explanation out of the way, let's continue. Next, we take the number 150,354,127 and divide it by 2:
150,354,127 ÷ 2 = 75,177,063.5
If the quotient is a whole number, then 2 and 75,177,063.5 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 | 150,354,127 | |
| -1 | -150,354,127 |
Now, we try dividing 150,354,127 by 3:
150,354,127 ÷ 3 = 50,118,042.3333
If the quotient is a whole number, then 3 and 50,118,042.3333 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 | 150,354,127 | |
| -1 | -150,354,127 |
Let's try dividing by 4:
150,354,127 ÷ 4 = 37,588,531.75
If the quotient is a whole number, then 4 and 37,588,531.75 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 | 150,354,127 | |
| -1 | 150,354,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 173 | 1,211 | 1,903 | 11,287 | 13,321 | 79,009 | 124,157 | 869,099 | 1,952,651 | 13,668,557 | 21,479,161 | 150,354,127 |
| -1 | -7 | -11 | -77 | -173 | -1,211 | -1,903 | -11,287 | -13,321 | -79,009 | -124,157 | -869,099 | -1,952,651 | -13,668,557 | -21,479,161 | -150,354,127 |
