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 802,200,751, 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 | 802,200,751 | |
| -1 | -802,200,751 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 802,200,751.
Example:
1 x 802,200,751 = 802,200,751
and
-1 x -802,200,751 = 802,200,751
Notice both answers equal 802,200,751
With that explanation out of the way, let's continue. Next, we take the number 802,200,751 and divide it by 2:
802,200,751 ÷ 2 = 401,100,375.5
If the quotient is a whole number, then 2 and 401,100,375.5 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 | 802,200,751 | |
| -1 | -802,200,751 |
Now, we try dividing 802,200,751 by 3:
802,200,751 ÷ 3 = 267,400,250.3333
If the quotient is a whole number, then 3 and 267,400,250.3333 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 | 802,200,751 | |
| -1 | -802,200,751 |
Let's try dividing by 4:
802,200,751 ÷ 4 = 200,550,187.75
If the quotient is a whole number, then 4 and 200,550,187.75 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 | 802,200,751 | |
| -1 | 802,200,751 |
If you did it right, you will end up with this table:
| 1 | 11 | 163 | 541 | 827 | 1,793 | 5,951 | 9,097 | 88,183 | 134,801 | 447,407 | 970,013 | 1,482,811 | 4,921,477 | 72,927,341 | 802,200,751 |
| -1 | -11 | -163 | -541 | -827 | -1,793 | -5,951 | -9,097 | -88,183 | -134,801 | -447,407 | -970,013 | -1,482,811 | -4,921,477 | -72,927,341 | -802,200,751 |
