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 120,473,471, 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 | 120,473,471 | |
| -1 | -120,473,471 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,473,471.
Example:
1 x 120,473,471 = 120,473,471
and
-1 x -120,473,471 = 120,473,471
Notice both answers equal 120,473,471
With that explanation out of the way, let's continue. Next, we take the number 120,473,471 and divide it by 2:
120,473,471 ÷ 2 = 60,236,735.5
If the quotient is a whole number, then 2 and 60,236,735.5 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 | 120,473,471 | |
| -1 | -120,473,471 |
Now, we try dividing 120,473,471 by 3:
120,473,471 ÷ 3 = 40,157,823.6667
If the quotient is a whole number, then 3 and 40,157,823.6667 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 | 120,473,471 | |
| -1 | -120,473,471 |
Let's try dividing by 4:
120,473,471 ÷ 4 = 30,118,367.75
If the quotient is a whole number, then 4 and 30,118,367.75 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 | 120,473,471 | |
| -1 | 120,473,471 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 31 | 437 | 589 | 713 | 8,893 | 13,547 | 168,967 | 204,539 | 275,683 | 3,886,241 | 5,237,977 | 6,340,709 | 120,473,471 |
| -1 | -19 | -23 | -31 | -437 | -589 | -713 | -8,893 | -13,547 | -168,967 | -204,539 | -275,683 | -3,886,241 | -5,237,977 | -6,340,709 | -120,473,471 |
