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 245,110,219, 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 | 245,110,219 | |
-1 | -245,110,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,110,219.
Example:
1 x 245,110,219 = 245,110,219
and
-1 x -245,110,219 = 245,110,219
Notice both answers equal 245,110,219
With that explanation out of the way, let's continue. Next, we take the number 245,110,219 and divide it by 2:
245,110,219 ÷ 2 = 122,555,109.5
If the quotient is a whole number, then 2 and 122,555,109.5 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 | 245,110,219 | |
-1 | -245,110,219 |
Now, we try dividing 245,110,219 by 3:
245,110,219 ÷ 3 = 81,703,406.3333
If the quotient is a whole number, then 3 and 81,703,406.3333 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 | 245,110,219 | |
-1 | -245,110,219 |
Let's try dividing by 4:
245,110,219 ÷ 4 = 61,277,554.75
If the quotient is a whole number, then 4 and 61,277,554.75 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 | 245,110,219 | |
-1 | 245,110,219 |
If you did it right, you will end up with this table:
1 | 79 | 3,102,661 | 245,110,219 |
-1 | -79 | -3,102,661 | -245,110,219 |
