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 702,911, 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 | 702,911 | |
-1 | -702,911 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 702,911.
Example:
1 x 702,911 = 702,911
and
-1 x -702,911 = 702,911
Notice both answers equal 702,911
With that explanation out of the way, let's continue. Next, we take the number 702,911 and divide it by 2:
702,911 ÷ 2 = 351,455.5
If the quotient is a whole number, then 2 and 351,455.5 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 | 702,911 | |
-1 | -702,911 |
Now, we try dividing 702,911 by 3:
702,911 ÷ 3 = 234,303.6667
If the quotient is a whole number, then 3 and 234,303.6667 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 | 702,911 | |
-1 | -702,911 |
Let's try dividing by 4:
702,911 ÷ 4 = 175,727.75
If the quotient is a whole number, then 4 and 175,727.75 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 | 702,911 | |
-1 | 702,911 |
If you did it right, you will end up with this table:
1 | 11 | 63,901 | 702,911 |
-1 | -11 | -63,901 | -702,911 |
