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 51,051,017, 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 | 51,051,017 | |
| -1 | -51,051,017 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,051,017.
Example:
1 x 51,051,017 = 51,051,017
and
-1 x -51,051,017 = 51,051,017
Notice both answers equal 51,051,017
With that explanation out of the way, let's continue. Next, we take the number 51,051,017 and divide it by 2:
51,051,017 ÷ 2 = 25,525,508.5
If the quotient is a whole number, then 2 and 25,525,508.5 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 | 51,051,017 | |
| -1 | -51,051,017 |
Now, we try dividing 51,051,017 by 3:
51,051,017 ÷ 3 = 17,017,005.6667
If the quotient is a whole number, then 3 and 17,017,005.6667 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 | 51,051,017 | |
| -1 | -51,051,017 |
Let's try dividing by 4:
51,051,017 ÷ 4 = 12,762,754.25
If the quotient is a whole number, then 4 and 12,762,754.25 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 | 51,051,017 | |
| -1 | 51,051,017 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 73 | 527 | 1,241 | 1,327 | 2,263 | 22,559 | 38,471 | 41,137 | 96,871 | 699,329 | 1,646,807 | 3,003,001 | 51,051,017 |
| -1 | -17 | -31 | -73 | -527 | -1,241 | -1,327 | -2,263 | -22,559 | -38,471 | -41,137 | -96,871 | -699,329 | -1,646,807 | -3,003,001 | -51,051,017 |
