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 51,454,049, 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 | 51,454,049 | |
| -1 | -51,454,049 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,454,049.
Example:
1 x 51,454,049 = 51,454,049
and
-1 x -51,454,049 = 51,454,049
Notice both answers equal 51,454,049
With that explanation out of the way, let's continue. Next, we take the number 51,454,049 and divide it by 2:
51,454,049 ÷ 2 = 25,727,024.5
If the quotient is a whole number, then 2 and 25,727,024.5 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 | 51,454,049 | |
| -1 | -51,454,049 |
Now, we try dividing 51,454,049 by 3:
51,454,049 ÷ 3 = 17,151,349.6667
If the quotient is a whole number, then 3 and 17,151,349.6667 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 | 51,454,049 | |
| -1 | -51,454,049 |
Let's try dividing by 4:
51,454,049 ÷ 4 = 12,863,512.25
If the quotient is a whole number, then 4 and 12,863,512.25 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 | 51,454,049 | |
| -1 | 51,454,049 |
If you did it right, you will end up with this table:
| 1 | 47 | 61 | 131 | 137 | 2,867 | 6,157 | 6,439 | 7,991 | 8,357 | 17,947 | 375,577 | 392,779 | 843,509 | 1,094,767 | 51,454,049 |
| -1 | -47 | -61 | -131 | -137 | -2,867 | -6,157 | -6,439 | -7,991 | -8,357 | -17,947 | -375,577 | -392,779 | -843,509 | -1,094,767 | -51,454,049 |
