1. $26$ and  $91$

Factors of above numbers are:

$26 = 2 \times 13$

$91 = 7 \times 13$

Common factors are: 13

Hence HCF is: $13$

LCM is: $13 \times 2 \times 7 = 182$

2. $510$ and $92$

$92 = 2×2×23$

$510 = 2×3×5×17$

Common Factors are: $2$

Hence HCF is $2$

LCM = $2^2 \times 3 \times 5 \times 17 \times 23 = 23460$

3. $336$ and $54%

$336 = 2 × 2 × 2 × 2 × 3 × 7$

$54 = 2 × 3 × 3 × 3$

Highest Common Factor: $2 \times 3$

Hence HCF = $6$

LCM Would be $= 2^4 \times 3 \times 7 \times 2 \times 3 \times 3 \times 3 = 3024$
