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 611,503, 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 | 611,503 | |
-1 | -611,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 611,503.
Example:
1 x 611,503 = 611,503
and
-1 x -611,503 = 611,503
Notice both answers equal 611,503
With that explanation out of the way, let's continue. Next, we take the number 611,503 and divide it by 2:
611,503 ÷ 2 = 305,751.5
If the quotient is a whole number, then 2 and 305,751.5 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 | 611,503 | |
-1 | -611,503 |
Now, we try dividing 611,503 by 3:
611,503 ÷ 3 = 203,834.3333
If the quotient is a whole number, then 3 and 203,834.3333 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 | 611,503 | |
-1 | -611,503 |
Let's try dividing by 4:
611,503 ÷ 4 = 152,875.75
If the quotient is a whole number, then 4 and 152,875.75 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 | 611,503 | |
-1 | 611,503 |
If you did it right, you will end up with this table:
1 | 43 | 14,221 | 611,503 |
-1 | -43 | -14,221 | -611,503 |
