Heya!
Here,s is ur answer related to☜☆☞⌐╦╦═─
11∗13∗15∗17+17=17(11∗13∗15∗1+1)11∗13∗15∗17+17=17(11∗13∗15∗1+1)
Now, 11∗13∗15∗111∗13∗15∗1 is a product of odd numbers which is always odd.
Thus, we have 17∗(odd+1)17∗(odd+1)
=odd∗(odd+odd)=odd∗(odd+odd)
=odd∗even=odd∗even
=even=even
Now, 2 is the only prime number that is even. Hence, given number cannot be prime and is therefore composite.
