Question

how to solve it step by step

Answer 1

Answer:

you have to find the hcf(highest common factor)here

Step-by-step explanation:

for finding the minimum factor we will find the hcf of 28,36,32

                             2     28,36,32

                             2     14,18,16

                                    7,9,8

hcf =2x2=4

therefore number of minimum books required for each class are 4 .
