3. Explain why 7 x 11 x 13 + 13 is a compositen
​

Answer 1

Answer:

Since , 7 x 11 x 13 + 13 has three factors ie. 13 , 7 and 11 so it is a composite number.

Step-by-step explanation:

7 x 11 x 13 + 13

= 13 (7 x 11 + 1)

= 13 x 77

= 13 x 7 x 11

Since , 7 x 11 x 13 + 13 has three factors ie. 13 , 7 and 11 so it is a composite number.
