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 1,338,761, 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 | 1,338,761 | |
-1 | -1,338,761 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,338,761.
Example:
1 x 1,338,761 = 1,338,761
and
-1 x -1,338,761 = 1,338,761
Notice both answers equal 1,338,761
With that explanation out of the way, let's continue. Next, we take the number 1,338,761 and divide it by 2:
1,338,761 ÷ 2 = 669,380.5
If the quotient is a whole number, then 2 and 669,380.5 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 | 1,338,761 | |
-1 | -1,338,761 |
Now, we try dividing 1,338,761 by 3:
1,338,761 ÷ 3 = 446,253.6667
If the quotient is a whole number, then 3 and 446,253.6667 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 | 1,338,761 | |
-1 | -1,338,761 |
Let's try dividing by 4:
1,338,761 ÷ 4 = 334,690.25
If the quotient is a whole number, then 4 and 334,690.25 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 | 1,338,761 | |
-1 | 1,338,761 |
If you did it right, you will end up with this table:
1 | 23 | 58,207 | 1,338,761 |
-1 | -23 | -58,207 | -1,338,761 |
