​

Answer 1

Answer:

becoz they are composite no.

Answer 2

Step-by-step explanation:

Follow these steps:

$13 \times 11 \times 5 + 13$

Take 13 common:

$13(11 \times 5 + 1)$

$13(55 + 1)$

$13(56)$

Now, factorise 56 into its prime factors:

$13 \times 2 \times 2 \times 2 \times 7$

Hence clearly we can see that it has 3 factors, therefore it is a composite number.
