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 150,477,257, 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 | 150,477,257 | |
| -1 | -150,477,257 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,477,257.
Example:
1 x 150,477,257 = 150,477,257
and
-1 x -150,477,257 = 150,477,257
Notice both answers equal 150,477,257
With that explanation out of the way, let's continue. Next, we take the number 150,477,257 and divide it by 2:
150,477,257 ÷ 2 = 75,238,628.5
If the quotient is a whole number, then 2 and 75,238,628.5 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 | 150,477,257 | |
| -1 | -150,477,257 |
Now, we try dividing 150,477,257 by 3:
150,477,257 ÷ 3 = 50,159,085.6667
If the quotient is a whole number, then 3 and 50,159,085.6667 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 | 150,477,257 | |
| -1 | -150,477,257 |
Let's try dividing by 4:
150,477,257 ÷ 4 = 37,619,314.25
If the quotient is a whole number, then 4 and 37,619,314.25 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 | 150,477,257 | |
| -1 | 150,477,257 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 83 | 287 | 581 | 3,403 | 6,317 | 23,821 | 44,219 | 258,997 | 524,311 | 1,812,979 | 3,670,177 | 21,496,751 | 150,477,257 |
| -1 | -7 | -41 | -83 | -287 | -581 | -3,403 | -6,317 | -23,821 | -44,219 | -258,997 | -524,311 | -1,812,979 | -3,670,177 | -21,496,751 | -150,477,257 |
