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 150,524,645, 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 | 150,524,645 | |
| -1 | -150,524,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,524,645.
Example:
1 x 150,524,645 = 150,524,645
and
-1 x -150,524,645 = 150,524,645
Notice both answers equal 150,524,645
With that explanation out of the way, let's continue. Next, we take the number 150,524,645 and divide it by 2:
150,524,645 ÷ 2 = 75,262,322.5
If the quotient is a whole number, then 2 and 75,262,322.5 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 | 150,524,645 | |
| -1 | -150,524,645 |
Now, we try dividing 150,524,645 by 3:
150,524,645 ÷ 3 = 50,174,881.6667
If the quotient is a whole number, then 3 and 50,174,881.6667 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 | 150,524,645 | |
| -1 | -150,524,645 |
Let's try dividing by 4:
150,524,645 ÷ 4 = 37,631,161.25
If the quotient is a whole number, then 4 and 37,631,161.25 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 | 150,524,645 | |
| -1 | 150,524,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 853 | 1,217 | 4,265 | 6,085 | 24,737 | 35,293 | 123,685 | 176,465 | 1,038,101 | 5,190,505 | 30,104,929 | 150,524,645 |
| -1 | -5 | -29 | -145 | -853 | -1,217 | -4,265 | -6,085 | -24,737 | -35,293 | -123,685 | -176,465 | -1,038,101 | -5,190,505 | -30,104,929 | -150,524,645 |
