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 651,051,017, 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 | 651,051,017 | |
| -1 | -651,051,017 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 651,051,017.
Example:
1 x 651,051,017 = 651,051,017
and
-1 x -651,051,017 = 651,051,017
Notice both answers equal 651,051,017
With that explanation out of the way, let's continue. Next, we take the number 651,051,017 and divide it by 2:
651,051,017 ÷ 2 = 325,525,508.5
If the quotient is a whole number, then 2 and 325,525,508.5 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 | 651,051,017 | |
| -1 | -651,051,017 |
Now, we try dividing 651,051,017 by 3:
651,051,017 ÷ 3 = 217,017,005.6667
If the quotient is a whole number, then 3 and 217,017,005.6667 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 | 651,051,017 | |
| -1 | -651,051,017 |
Let's try dividing by 4:
651,051,017 ÷ 4 = 162,762,754.25
If the quotient is a whole number, then 4 and 162,762,754.25 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 | 651,051,017 | |
| -1 | 651,051,017 |
If you did it right, you will end up with this table:
| 1 | 19 | 59 | 389 | 1,121 | 1,493 | 7,391 | 22,951 | 28,367 | 88,087 | 436,069 | 580,777 | 1,673,653 | 11,034,763 | 34,265,843 | 651,051,017 |
| -1 | -19 | -59 | -389 | -1,121 | -1,493 | -7,391 | -22,951 | -28,367 | -88,087 | -436,069 | -580,777 | -1,673,653 | -11,034,763 | -34,265,843 | -651,051,017 |
