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 5,450,419, 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 | 5,450,419 | |
-1 | -5,450,419 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,450,419.
Example:
1 x 5,450,419 = 5,450,419
and
-1 x -5,450,419 = 5,450,419
Notice both answers equal 5,450,419
With that explanation out of the way, let's continue. Next, we take the number 5,450,419 and divide it by 2:
5,450,419 ÷ 2 = 2,725,209.5
If the quotient is a whole number, then 2 and 2,725,209.5 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 | 5,450,419 | |
-1 | -5,450,419 |
Now, we try dividing 5,450,419 by 3:
5,450,419 ÷ 3 = 1,816,806.3333
If the quotient is a whole number, then 3 and 1,816,806.3333 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 | 5,450,419 | |
-1 | -5,450,419 |
Let's try dividing by 4:
5,450,419 ÷ 4 = 1,362,604.75
If the quotient is a whole number, then 4 and 1,362,604.75 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 | 5,450,419 | |
-1 | 5,450,419 |
If you did it right, you will end up with this table:
1 | 13 | 169 | 32,251 | 419,263 | 5,450,419 |
-1 | -13 | -169 | -32,251 | -419,263 | -5,450,419 |
