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 702,063,665, 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 | 702,063,665 | |
| -1 | -702,063,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 702,063,665.
Example:
1 x 702,063,665 = 702,063,665
and
-1 x -702,063,665 = 702,063,665
Notice both answers equal 702,063,665
With that explanation out of the way, let's continue. Next, we take the number 702,063,665 and divide it by 2:
702,063,665 ÷ 2 = 351,031,832.5
If the quotient is a whole number, then 2 and 351,031,832.5 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 | 702,063,665 | |
| -1 | -702,063,665 |
Now, we try dividing 702,063,665 by 3:
702,063,665 ÷ 3 = 234,021,221.6667
If the quotient is a whole number, then 3 and 234,021,221.6667 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 | 702,063,665 | |
| -1 | -702,063,665 |
Let's try dividing by 4:
702,063,665 ÷ 4 = 175,515,916.25
If the quotient is a whole number, then 4 and 175,515,916.25 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 | 702,063,665 | |
| -1 | 702,063,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 1,063 | 4,261 | 5,315 | 21,305 | 32,953 | 132,091 | 164,765 | 660,455 | 4,529,443 | 22,647,215 | 140,412,733 | 702,063,665 |
| -1 | -5 | -31 | -155 | -1,063 | -4,261 | -5,315 | -21,305 | -32,953 | -132,091 | -164,765 | -660,455 | -4,529,443 | -22,647,215 | -140,412,733 | -702,063,665 |
