MCQ
The common factor of $8 a^{2} b^{4} c^{2}, 12 a^{4} b c^{4}$ and $20 a^{3} b^{4}$ is
- A$a^{4} b^{4}$
- B$a^{2} b^{2}$
- C$4 a^{2} b^{2}$
- ✓$4 a^{2} b$
✓
Answer
Correct option: D.
$4 a^{2} b$
d
$8 a^{2} b^{4} c^{2}=2 \times 2 \times 2 \times a \times a \times b \times b \times b \times b \times c \times c$
$12 a^{4} b c^{2}=2 \times 2 \times 3 \times a \times a \times a \times a \times b \times c \times c$
$20 a^{3} b^{4}=2 \times 2 \times 5 \times a \times a \times a \times b \times b \times b \times b$
$8 a^{2} b^{4} c^{2}=2 \times 2 \times 2 \times a \times a \times b \times b \times b \times b \times c \times c$
$12 a^{4} b c^{2}=2 \times 2 \times 3 \times a \times a \times a \times a \times b \times c \times c$
$20 a^{3} b^{4}=2 \times 2 \times 5 \times a \times a \times a \times b \times b \times b \times b$
