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 51,025,645, 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 | 51,025,645 | |
| -1 | -51,025,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,025,645.
Example:
1 x 51,025,645 = 51,025,645
and
-1 x -51,025,645 = 51,025,645
Notice both answers equal 51,025,645
With that explanation out of the way, let's continue. Next, we take the number 51,025,645 and divide it by 2:
51,025,645 ÷ 2 = 25,512,822.5
If the quotient is a whole number, then 2 and 25,512,822.5 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 | 51,025,645 | |
| -1 | -51,025,645 |
Now, we try dividing 51,025,645 by 3:
51,025,645 ÷ 3 = 17,008,548.3333
If the quotient is a whole number, then 3 and 17,008,548.3333 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 | 51,025,645 | |
| -1 | -51,025,645 |
Let's try dividing by 4:
51,025,645 ÷ 4 = 12,756,411.25
If the quotient is a whole number, then 4 and 12,756,411.25 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 | 51,025,645 | |
| -1 | 51,025,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 31,991 | 159,955 | 351,901 | 927,739 | 1,759,505 | 4,638,695 | 10,205,129 | 51,025,645 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -31,991 | -159,955 | -351,901 | -927,739 | -1,759,505 | -4,638,695 | -10,205,129 | -51,025,645 |
