2. 312
3. 234
4. 468

Answer 1

Correct Answer - Option 1 : 156

Given:

We have to find LCM of 52, 78 and 156

Concept used:

Prime factorization concept

Calculation:

52 = 2² × 13¹

78 = 2¹ × 3¹ × 13¹

156 = 2² × 3¹ × 13¹

Now we have to take factors which occur most often

LCM = 2² × 3¹ × 13¹

⇒ LCM = 4 × 3 × 13

⇒ LCM = 156

∴ Required LCM is 156
