of each subject. find the number of shells that can be used. what would be the number of these books in each shelf? ​

Answer 1

Answer:

From the question,

Number of English book =780

Number of Science book =364

Now, find the factors of 780 and 364

The factors of 780=2×2×3×5×13

The factors of 364=2×2×7×13

∴ The HCF of 780 and 364=2×2×13=52

Hence, the minimum number of book in each self =52.
