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 150,251,761, 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 | 150,251,761 | |
| -1 | -150,251,761 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,251,761.
Example:
1 x 150,251,761 = 150,251,761
and
-1 x -150,251,761 = 150,251,761
Notice both answers equal 150,251,761
With that explanation out of the way, let's continue. Next, we take the number 150,251,761 and divide it by 2:
150,251,761 ÷ 2 = 75,125,880.5
If the quotient is a whole number, then 2 and 75,125,880.5 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 | 150,251,761 | |
| -1 | -150,251,761 |
Now, we try dividing 150,251,761 by 3:
150,251,761 ÷ 3 = 50,083,920.3333
If the quotient is a whole number, then 3 and 50,083,920.3333 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 | 150,251,761 | |
| -1 | -150,251,761 |
Let's try dividing by 4:
150,251,761 ÷ 4 = 37,562,940.25
If the quotient is a whole number, then 4 and 37,562,940.25 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 | 150,251,761 | |
| -1 | 150,251,761 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 43 | 341 | 473 | 1,333 | 10,247 | 14,663 | 112,717 | 317,657 | 440,621 | 3,494,227 | 4,846,831 | 13,659,251 | 150,251,761 |
| -1 | -11 | -31 | -43 | -341 | -473 | -1,333 | -10,247 | -14,663 | -112,717 | -317,657 | -440,621 | -3,494,227 | -4,846,831 | -13,659,251 | -150,251,761 |
