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 17,223,541, 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 | 17,223,541 | |
-1 | -17,223,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,223,541.
Example:
1 x 17,223,541 = 17,223,541
and
-1 x -17,223,541 = 17,223,541
Notice both answers equal 17,223,541
With that explanation out of the way, let's continue. Next, we take the number 17,223,541 and divide it by 2:
17,223,541 ÷ 2 = 8,611,770.5
If the quotient is a whole number, then 2 and 8,611,770.5 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 | 17,223,541 | |
-1 | -17,223,541 |
Now, we try dividing 17,223,541 by 3:
17,223,541 ÷ 3 = 5,741,180.3333
If the quotient is a whole number, then 3 and 5,741,180.3333 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 | 17,223,541 | |
-1 | -17,223,541 |
Let's try dividing by 4:
17,223,541 ÷ 4 = 4,305,885.25
If the quotient is a whole number, then 4 and 4,305,885.25 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 | 17,223,541 | |
-1 | 17,223,541 |
If you did it right, you will end up with this table:
1 | 1,201 | 14,341 | 17,223,541 |
-1 | -1,201 | -14,341 | -17,223,541 |
