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 254,054,047, 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 | 254,054,047 | |
-1 | -254,054,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,054,047.
Example:
1 x 254,054,047 = 254,054,047
and
-1 x -254,054,047 = 254,054,047
Notice both answers equal 254,054,047
With that explanation out of the way, let's continue. Next, we take the number 254,054,047 and divide it by 2:
254,054,047 ÷ 2 = 127,027,023.5
If the quotient is a whole number, then 2 and 127,027,023.5 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 | 254,054,047 | |
-1 | -254,054,047 |
Now, we try dividing 254,054,047 by 3:
254,054,047 ÷ 3 = 84,684,682.3333
If the quotient is a whole number, then 3 and 84,684,682.3333 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 | 254,054,047 | |
-1 | -254,054,047 |
Let's try dividing by 4:
254,054,047 ÷ 4 = 63,513,511.75
If the quotient is a whole number, then 4 and 63,513,511.75 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 | 254,054,047 | |
-1 | 254,054,047 |
If you did it right, you will end up with this table:
1 | 13 | 19,542,619 | 254,054,047 |
-1 | -13 | -19,542,619 | -254,054,047 |
