Question

explain why 7×11×13×15+11 is composite number​

Answer 1

Step-by-step explanation:

First of all, the number is in an equation. So, solve it

7 x 11 x 13 x 15 + 11

= 11 [ (7 x 13 x 15) + 1 ]                       (11 is common)

= 11 (1365 + 1)

= 11 x 1366 x 1

The number which is going to form, will have factors more than two.

Therefore, the number formed will be a composite number.
