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 17,619,043, 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 | 17,619,043 | |
-1 | -17,619,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,619,043.
Example:
1 x 17,619,043 = 17,619,043
and
-1 x -17,619,043 = 17,619,043
Notice both answers equal 17,619,043
With that explanation out of the way, let's continue. Next, we take the number 17,619,043 and divide it by 2:
17,619,043 ÷ 2 = 8,809,521.5
If the quotient is a whole number, then 2 and 8,809,521.5 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 | 17,619,043 | |
-1 | -17,619,043 |
Now, we try dividing 17,619,043 by 3:
17,619,043 ÷ 3 = 5,873,014.3333
If the quotient is a whole number, then 3 and 5,873,014.3333 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 | 17,619,043 | |
-1 | -17,619,043 |
Let's try dividing by 4:
17,619,043 ÷ 4 = 4,404,760.75
If the quotient is a whole number, then 4 and 4,404,760.75 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 | 17,619,043 | |
-1 | 17,619,043 |
If you did it right, you will end up with this table:
1 | 13 | 1,355,311 | 17,619,043 |
-1 | -13 | -1,355,311 | -17,619,043 |
