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 554,729, 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 | 554,729 | |
-1 | -554,729 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 554,729.
Example:
1 x 554,729 = 554,729
and
-1 x -554,729 = 554,729
Notice both answers equal 554,729
With that explanation out of the way, let's continue. Next, we take the number 554,729 and divide it by 2:
554,729 ÷ 2 = 277,364.5
If the quotient is a whole number, then 2 and 277,364.5 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 | 554,729 | |
-1 | -554,729 |
Now, we try dividing 554,729 by 3:
554,729 ÷ 3 = 184,909.6667
If the quotient is a whole number, then 3 and 184,909.6667 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 | 554,729 | |
-1 | -554,729 |
Let's try dividing by 4:
554,729 ÷ 4 = 138,682.25
If the quotient is a whole number, then 4 and 138,682.25 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 | 554,729 | |
-1 | 554,729 |
If you did it right, you will end up with this table:
1 | 7 | 49 | 11,321 | 79,247 | 554,729 |
-1 | -7 | -49 | -11,321 | -79,247 | -554,729 |
