Answer 1

Answer:

12a^2b^2=3×2×2×a×a×b×b

30ab=3×2×5×a×b

so, HCF is 3×2×a×b=6ab

Answer 2

Answer:

6ab

Step-by-step explanation:

We need to find the HCF of 12a²b² and 30ab.

Let's start factorising !

• 12a²b² = 2 × 3 × a² × b²

• 30ab = 2 × 3 × 5 × a × b

HCF(12a²b²,30ab) = 2 × 3 × a × b = 6ab
