Solution

Find the HCF of the given numbers
HCF or the highest common factor of two numbers is the largest number which is a factor of both the numbers.
Factorise $91, 112, 49$
$91 = 7 \times 13$
$112 = 2 \times 2 \times 2 \times 2 \times 7$
$49 = 7 \times 7$
Common divisor of $91, 112, 49$ is $7$
Hence, HCF of $91, 112, 49$ is $7$ .
