Find the greatest common factor (GCF) of 36, 84, and 90 by finding the prime factorization of each to determine which prime factors they share. Therefore, a 6 liter vessel is the capacity of the greatest vessel which can be used to fill each an exact number of times.
Counterexample:

4 is not a prime number. So, it's false.

ran 4/5 miles. We need to find the tenths that is present to the given number
which is 4/5.
4/5 is a fraction, and since we are looking for tenths which is a decimal
value. Thus, we need to convert this fraction to decimals.
To convert, simply divide the numerator by the denominator.
In the given number, 4 is our numerator and 5 is our denominator.
=> 4 / 5
=> 0.8
Therefore, 8 is the value of tenths because it is the number next to the
decimal point.
