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 150,850,865, 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 | 150,850,865 | |
| -1 | -150,850,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,850,865.
Example:
1 x 150,850,865 = 150,850,865
and
-1 x -150,850,865 = 150,850,865
Notice both answers equal 150,850,865
With that explanation out of the way, let's continue. Next, we take the number 150,850,865 and divide it by 2:
150,850,865 ÷ 2 = 75,425,432.5
If the quotient is a whole number, then 2 and 75,425,432.5 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 | 150,850,865 | |
| -1 | -150,850,865 |
Now, we try dividing 150,850,865 by 3:
150,850,865 ÷ 3 = 50,283,621.6667
If the quotient is a whole number, then 3 and 50,283,621.6667 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 | 150,850,865 | |
| -1 | -150,850,865 |
Let's try dividing by 4:
150,850,865 ÷ 4 = 37,712,716.25
If the quotient is a whole number, then 4 and 37,712,716.25 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 | 150,850,865 | |
| -1 | 150,850,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 305 | 671 | 3,355 | 44,963 | 224,815 | 494,593 | 2,472,965 | 2,742,743 | 13,713,715 | 30,170,173 | 150,850,865 |
| -1 | -5 | -11 | -55 | -61 | -305 | -671 | -3,355 | -44,963 | -224,815 | -494,593 | -2,472,965 | -2,742,743 | -13,713,715 | -30,170,173 | -150,850,865 |
