Answer 2

Answer:

HCF of $912$ and $1216$  is $304$ . Option (a) 304 is correct .

Step-by-step explanation:

To find : HCF of and .

Solution :  

• HCF is the highest common factor also called as greatest common divisor ,( GCD ).
• We find HCF by prime factorization method in this method we find prime factors of given numbers .  
• Therefore to find HCF of $912$ and $1216$ we find prime factors of these numbers .
• Prime factors of $912 = 2\times 2\times 2\times 2\times 3\times 19$
• Prime factors of $1216 = 2\times 2\times 2\times 2\times 2\times 2\times 19$
• HCF of $912$ and $1216$ = $2\times 2\times 2\times 2\times 19$

                                          $= 304$
