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 100,422,101, 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 | 100,422,101 | |
-1 | -100,422,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,422,101.
Example:
1 x 100,422,101 = 100,422,101
and
-1 x -100,422,101 = 100,422,101
Notice both answers equal 100,422,101
With that explanation out of the way, let's continue. Next, we take the number 100,422,101 and divide it by 2:
100,422,101 ÷ 2 = 50,211,050.5
If the quotient is a whole number, then 2 and 50,211,050.5 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 | 100,422,101 | |
-1 | -100,422,101 |
Now, we try dividing 100,422,101 by 3:
100,422,101 ÷ 3 = 33,474,033.6667
If the quotient is a whole number, then 3 and 33,474,033.6667 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 | 100,422,101 | |
-1 | -100,422,101 |
Let's try dividing by 4:
100,422,101 ÷ 4 = 25,105,525.25
If the quotient is a whole number, then 4 and 25,105,525.25 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 | 100,422,101 | |
-1 | 100,422,101 |
If you did it right, you will end up with this table:
1 | 13 | 7,724,777 | 100,422,101 |
-1 | -13 | -7,724,777 | -100,422,101 |
