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 702,200,375, 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 | 702,200,375 | |
| -1 | -702,200,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 702,200,375.
Example:
1 x 702,200,375 = 702,200,375
and
-1 x -702,200,375 = 702,200,375
Notice both answers equal 702,200,375
With that explanation out of the way, let's continue. Next, we take the number 702,200,375 and divide it by 2:
702,200,375 ÷ 2 = 351,100,187.5
If the quotient is a whole number, then 2 and 351,100,187.5 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 | 702,200,375 | |
| -1 | -702,200,375 |
Now, we try dividing 702,200,375 by 3:
702,200,375 ÷ 3 = 234,066,791.6667
If the quotient is a whole number, then 3 and 234,066,791.6667 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 | 702,200,375 | |
| -1 | -702,200,375 |
Let's try dividing by 4:
702,200,375 ÷ 4 = 175,550,093.75
If the quotient is a whole number, then 4 and 175,550,093.75 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 | 702,200,375 | |
| -1 | 702,200,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 125 | 155 | 775 | 3,875 | 181,213 | 906,065 | 4,530,325 | 5,617,603 | 22,651,625 | 28,088,015 | 140,440,075 | 702,200,375 |
| -1 | -5 | -25 | -31 | -125 | -155 | -775 | -3,875 | -181,213 | -906,065 | -4,530,325 | -5,617,603 | -22,651,625 | -28,088,015 | -140,440,075 | -702,200,375 |
