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 705,203,075, 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 | 705,203,075 | |
| -1 | -705,203,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 705,203,075.
Example:
1 x 705,203,075 = 705,203,075
and
-1 x -705,203,075 = 705,203,075
Notice both answers equal 705,203,075
With that explanation out of the way, let's continue. Next, we take the number 705,203,075 and divide it by 2:
705,203,075 ÷ 2 = 352,601,537.5
If the quotient is a whole number, then 2 and 352,601,537.5 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 | 705,203,075 | |
| -1 | -705,203,075 |
Now, we try dividing 705,203,075 by 3:
705,203,075 ÷ 3 = 235,067,691.6667
If the quotient is a whole number, then 3 and 235,067,691.6667 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 | 705,203,075 | |
| -1 | -705,203,075 |
Let's try dividing by 4:
705,203,075 ÷ 4 = 176,300,768.75
If the quotient is a whole number, then 4 and 176,300,768.75 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 | 705,203,075 | |
| -1 | 705,203,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 205 | 1,025 | 688,003 | 3,440,015 | 17,200,075 | 28,208,123 | 141,040,615 | 705,203,075 |
| -1 | -5 | -25 | -41 | -205 | -1,025 | -688,003 | -3,440,015 | -17,200,075 | -28,208,123 | -141,040,615 | -705,203,075 |
