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 151,332,433, 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 | 151,332,433 | |
| -1 | -151,332,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,332,433.
Example:
1 x 151,332,433 = 151,332,433
and
-1 x -151,332,433 = 151,332,433
Notice both answers equal 151,332,433
With that explanation out of the way, let's continue. Next, we take the number 151,332,433 and divide it by 2:
151,332,433 ÷ 2 = 75,666,216.5
If the quotient is a whole number, then 2 and 75,666,216.5 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 | 151,332,433 | |
| -1 | -151,332,433 |
Now, we try dividing 151,332,433 by 3:
151,332,433 ÷ 3 = 50,444,144.3333
If the quotient is a whole number, then 3 and 50,444,144.3333 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 | 151,332,433 | |
| -1 | -151,332,433 |
Let's try dividing by 4:
151,332,433 ÷ 4 = 37,833,108.25
If the quotient is a whole number, then 4 and 37,833,108.25 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 | 151,332,433 | |
| -1 | 151,332,433 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 47 | 49 | 161 | 329 | 1,081 | 1,127 | 2,303 | 2,857 | 7,567 | 19,999 | 52,969 | 65,711 | 134,279 | 139,993 | 459,977 | 939,953 | 3,088,417 | 3,219,839 | 6,579,671 | 21,618,919 | 151,332,433 |
| -1 | -7 | -23 | -47 | -49 | -161 | -329 | -1,081 | -1,127 | -2,303 | -2,857 | -7,567 | -19,999 | -52,969 | -65,711 | -134,279 | -139,993 | -459,977 | -939,953 | -3,088,417 | -3,219,839 | -6,579,671 | -21,618,919 | -151,332,433 |
