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 32,047,457, 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 | 32,047,457 | |
| -1 | -32,047,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,047,457.
Example:
1 x 32,047,457 = 32,047,457
and
-1 x -32,047,457 = 32,047,457
Notice both answers equal 32,047,457
With that explanation out of the way, let's continue. Next, we take the number 32,047,457 and divide it by 2:
32,047,457 ÷ 2 = 16,023,728.5
If the quotient is a whole number, then 2 and 16,023,728.5 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 | 32,047,457 | |
| -1 | -32,047,457 |
Now, we try dividing 32,047,457 by 3:
32,047,457 ÷ 3 = 10,682,485.6667
If the quotient is a whole number, then 3 and 10,682,485.6667 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 | 32,047,457 | |
| -1 | -32,047,457 |
Let's try dividing by 4:
32,047,457 ÷ 4 = 8,011,864.25
If the quotient is a whole number, then 4 and 8,011,864.25 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 | 32,047,457 | |
| -1 | 32,047,457 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 193 | 241 | 689 | 2,509 | 3,133 | 10,229 | 12,773 | 46,513 | 132,977 | 166,049 | 604,669 | 2,465,189 | 32,047,457 |
| -1 | -13 | -53 | -193 | -241 | -689 | -2,509 | -3,133 | -10,229 | -12,773 | -46,513 | -132,977 | -166,049 | -604,669 | -2,465,189 | -32,047,457 |
