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 51,645,005, 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 | 51,645,005 | |
| -1 | -51,645,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,645,005.
Example:
1 x 51,645,005 = 51,645,005
and
-1 x -51,645,005 = 51,645,005
Notice both answers equal 51,645,005
With that explanation out of the way, let's continue. Next, we take the number 51,645,005 and divide it by 2:
51,645,005 ÷ 2 = 25,822,502.5
If the quotient is a whole number, then 2 and 25,822,502.5 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 | 51,645,005 | |
| -1 | -51,645,005 |
Now, we try dividing 51,645,005 by 3:
51,645,005 ÷ 3 = 17,215,001.6667
If the quotient is a whole number, then 3 and 17,215,001.6667 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 | 51,645,005 | |
| -1 | -51,645,005 |
Let's try dividing by 4:
51,645,005 ÷ 4 = 12,911,251.25
If the quotient is a whole number, then 4 and 12,911,251.25 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 | 51,645,005 | |
| -1 | 51,645,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 547 | 821 | 2,735 | 4,105 | 12,581 | 18,883 | 62,905 | 94,415 | 449,087 | 2,245,435 | 10,329,001 | 51,645,005 |
| -1 | -5 | -23 | -115 | -547 | -821 | -2,735 | -4,105 | -12,581 | -18,883 | -62,905 | -94,415 | -449,087 | -2,245,435 | -10,329,001 | -51,645,005 |
