Question

find the HCF by prime factorisation method 120,108and96​

Answer 1

Answer:

8

Step-by-step explanation:

Let us first obtain the factor of 120, 108 and 96.

$120=2*2*2*3*5\\108=2*2*3*3*3\\96=2*2*2*2*2*3$

From above, $2*2*3=8$ is common.

∴ 8 is the HCF of 120, 108 and 96​.

                         

Answer 2

Answer:

12

Step-by-step explanation:

prime factorisation of

120=2^3*3*5

108=2^2*3^3

96=2^5*3

hence answer is 12(3*2^2)
