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 131,002,333, 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 | 131,002,333 | |
| -1 | -131,002,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,002,333.
Example:
1 x 131,002,333 = 131,002,333
and
-1 x -131,002,333 = 131,002,333
Notice both answers equal 131,002,333
With that explanation out of the way, let's continue. Next, we take the number 131,002,333 and divide it by 2:
131,002,333 ÷ 2 = 65,501,166.5
If the quotient is a whole number, then 2 and 65,501,166.5 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 | 131,002,333 | |
| -1 | -131,002,333 |
Now, we try dividing 131,002,333 by 3:
131,002,333 ÷ 3 = 43,667,444.3333
If the quotient is a whole number, then 3 and 43,667,444.3333 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 | 131,002,333 | |
| -1 | -131,002,333 |
Let's try dividing by 4:
131,002,333 ÷ 4 = 32,750,583.25
If the quotient is a whole number, then 4 and 32,750,583.25 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 | 131,002,333 | |
| -1 | 131,002,333 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 343 | 539 | 3,773 | 34,721 | 243,047 | 381,931 | 1,701,329 | 2,673,517 | 11,909,303 | 18,714,619 | 131,002,333 |
| -1 | -7 | -11 | -49 | -77 | -343 | -539 | -3,773 | -34,721 | -243,047 | -381,931 | -1,701,329 | -2,673,517 | -11,909,303 | -18,714,619 | -131,002,333 |
