Question

find the LCM of 34 , 85 , and 51 with method

Answer 1

To find : LCM of $34 , 85 ,51$

Solution :

• LCM is the least common multiple of number .
• We use prime factorization method to find LCM .  
• To find the LCM of  n $34 , 85 ,51$  we find prime factors of $34 , 85 ,51$  .
• Prime factors of $34 = 2\times 17$
• Prime factors of $85 = 5\times 17$
• Prime factors of $51 = 3\times 17$
• LCM of $34 , 85 ,51$ = $2\times 3\times 5\times 17$

                                   $= 510$

Hence . LCM of $34 , 85 ,51$ is $510$ .
