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 210,451,603, 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 | 210,451,603 | |
-1 | -210,451,603 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 210,451,603.
Example:
1 x 210,451,603 = 210,451,603
and
-1 x -210,451,603 = 210,451,603
Notice both answers equal 210,451,603
With that explanation out of the way, let's continue. Next, we take the number 210,451,603 and divide it by 2:
210,451,603 ÷ 2 = 105,225,801.5
If the quotient is a whole number, then 2 and 105,225,801.5 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 | 210,451,603 | |
-1 | -210,451,603 |
Now, we try dividing 210,451,603 by 3:
210,451,603 ÷ 3 = 70,150,534.3333
If the quotient is a whole number, then 3 and 70,150,534.3333 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 | 210,451,603 | |
-1 | -210,451,603 |
Let's try dividing by 4:
210,451,603 ÷ 4 = 52,612,900.75
If the quotient is a whole number, then 4 and 52,612,900.75 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 | 210,451,603 | |
-1 | 210,451,603 |
If you did it right, you will end up with this table:
1 | 1,109 | 189,767 | 210,451,603 |
-1 | -1,109 | -189,767 | -210,451,603 |
