Answer with explanation:
Two numbers are , 24 a³b and 36 a b².
The meaning of G C F between two number is that greatest number which divide both the number.
We will factorize , 24 a³b and 36 a b² and take out the common factors to determine their G CF.
→24 a³ b= 2×2×2×3×a×a×a×b
→36 a b²=2×2×3×3×a×b×b
G C F(Greatest common factor)=2×2×3×a×b
=12 a b
Option C
