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 20,053,675, 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 | 20,053,675 | |
-1 | -20,053,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,053,675.
Example:
1 x 20,053,675 = 20,053,675
and
-1 x -20,053,675 = 20,053,675
Notice both answers equal 20,053,675
With that explanation out of the way, let's continue. Next, we take the number 20,053,675 and divide it by 2:
20,053,675 ÷ 2 = 10,026,837.5
If the quotient is a whole number, then 2 and 10,026,837.5 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 | 20,053,675 | |
-1 | -20,053,675 |
Now, we try dividing 20,053,675 by 3:
20,053,675 ÷ 3 = 6,684,558.3333
If the quotient is a whole number, then 3 and 6,684,558.3333 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 | 20,053,675 | |
-1 | -20,053,675 |
Let's try dividing by 4:
20,053,675 ÷ 4 = 5,013,418.75
If the quotient is a whole number, then 4 and 5,013,418.75 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 | 20,053,675 | |
-1 | 20,053,675 |
If you did it right, you will end up with this table:
1 | 5 | 25 | 802,147 | 4,010,735 | 20,053,675 |
-1 | -5 | -25 | -802,147 | -4,010,735 | -20,053,675 |
