Question

Choose the correct answer from the alternatives given :
If a number is divisible by both $11and13$, then it must be necessarily

• A. $divisibleby(11+13)$
• B. $divisibleby(13-11)$
• C. divisible by ($11$ $\times$ $13$)
• D. $429$

Answer 1

Answer: (C)

divisible by ($11$ $\times$ $13$)

If a number is divisible by both 11 and 13, then it must be divisible by the product of these two number i.e. LCM of the two numbers
Hence number should be divisible by (11 $\times$ 13).
