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 25,055,777, 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 | 25,055,777 | |
-1 | -25,055,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,055,777.
Example:
1 x 25,055,777 = 25,055,777
and
-1 x -25,055,777 = 25,055,777
Notice both answers equal 25,055,777
With that explanation out of the way, let's continue. Next, we take the number 25,055,777 and divide it by 2:
25,055,777 ÷ 2 = 12,527,888.5
If the quotient is a whole number, then 2 and 12,527,888.5 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 | 25,055,777 | |
-1 | -25,055,777 |
Now, we try dividing 25,055,777 by 3:
25,055,777 ÷ 3 = 8,351,925.6667
If the quotient is a whole number, then 3 and 8,351,925.6667 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 | 25,055,777 | |
-1 | -25,055,777 |
Let's try dividing by 4:
25,055,777 ÷ 4 = 6,263,944.25
If the quotient is a whole number, then 4 and 6,263,944.25 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 | 25,055,777 | |
-1 | 25,055,777 |
If you did it right, you will end up with this table:
1 | 101 | 248,077 | 25,055,777 |
-1 | -101 | -248,077 | -25,055,777 |
