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 47,322,457, 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 | 47,322,457 | |
| -1 | -47,322,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,322,457.
Example:
1 x 47,322,457 = 47,322,457
and
-1 x -47,322,457 = 47,322,457
Notice both answers equal 47,322,457
With that explanation out of the way, let's continue. Next, we take the number 47,322,457 and divide it by 2:
47,322,457 ÷ 2 = 23,661,228.5
If the quotient is a whole number, then 2 and 23,661,228.5 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 | 47,322,457 | |
| -1 | -47,322,457 |
Now, we try dividing 47,322,457 by 3:
47,322,457 ÷ 3 = 15,774,152.3333
If the quotient is a whole number, then 3 and 15,774,152.3333 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 | 47,322,457 | |
| -1 | -47,322,457 |
Let's try dividing by 4:
47,322,457 ÷ 4 = 11,830,614.25
If the quotient is a whole number, then 4 and 11,830,614.25 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 | 47,322,457 | |
| -1 | 47,322,457 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 89 | 91 | 623 | 1,157 | 5,843 | 8,099 | 40,901 | 75,959 | 520,027 | 531,713 | 3,640,189 | 6,760,351 | 47,322,457 |
| -1 | -7 | -13 | -89 | -91 | -623 | -1,157 | -5,843 | -8,099 | -40,901 | -75,959 | -520,027 | -531,713 | -3,640,189 | -6,760,351 | -47,322,457 |
