class 6 Mathematics Textbook Chapter 5 question answer
Guna tested divisibility for 8 and 5 to conclude that 14560 is divisible by 2, 4, 5, 8, and 10. Divisibility by 8 ensures the number is divisible by 2 and 4, as 8 encompasses their factors. Similarly, divisibility by 5 guarantees divisibility by 10, since 10 = 2 × 5. These two tests are sufficient to confirm that the number is divisible by all five conditions without additional checks.
