Question

Explain why 5 x 11 x 17 +17 is a composite number while 7*6*5*3

Answer 1

Hi ,

Any number which has more than two factors

is called composite number.

5 × 11 × 17 + 17

= 17 ( 5 × 11 + 1 )

= 17 ( 55 + 1 )

= 17 × 56

= 17 × 56 × 1 ( More than two factors )

therefore ,

5 × 11 × 17 + 17 is a composite number.

I hope this helps you.
