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 147,407,311, 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 | 147,407,311 | |
| -1 | -147,407,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,407,311.
Example:
1 x 147,407,311 = 147,407,311
and
-1 x -147,407,311 = 147,407,311
Notice both answers equal 147,407,311
With that explanation out of the way, let's continue. Next, we take the number 147,407,311 and divide it by 2:
147,407,311 ÷ 2 = 73,703,655.5
If the quotient is a whole number, then 2 and 73,703,655.5 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 | 147,407,311 | |
| -1 | -147,407,311 |
Now, we try dividing 147,407,311 by 3:
147,407,311 ÷ 3 = 49,135,770.3333
If the quotient is a whole number, then 3 and 49,135,770.3333 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 | 147,407,311 | |
| -1 | -147,407,311 |
Let's try dividing by 4:
147,407,311 ÷ 4 = 36,851,827.75
If the quotient is a whole number, then 4 and 36,851,827.75 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 | 147,407,311 | |
| -1 | 147,407,311 |
If you did it right, you will end up with this table:
| 1 | 43 | 59 | 97 | 599 | 2,537 | 4,171 | 5,723 | 25,757 | 35,341 | 58,103 | 246,089 | 1,519,663 | 2,498,429 | 3,428,077 | 147,407,311 |
| -1 | -43 | -59 | -97 | -599 | -2,537 | -4,171 | -5,723 | -25,757 | -35,341 | -58,103 | -246,089 | -1,519,663 | -2,498,429 | -3,428,077 | -147,407,311 |
