Common factor of $17abc, 34ab^2, 51a^2b$ is:
A
$17abc$
✓
$17ab$
C
$17ac$
D
$17a^2b^2c$
✓
Answer
Correct option: B.
$17ab$
B. $17ab$ Solution:
Given, $17 a b c=17 \times a \times b \times c$
$34 a b^2=2 \times 17 \times a \times b \times b $
$34 a^2 b=3 \times 17 \times a \times a \times b$
Now, collecting the common factors, we get $17 \times a \times b=17 a b$
