13 x 23 x 29 + 13
all the numbers are odd prime
we know that product of two odd numbers is always odd.
so product of 13 and 23 will be an odd number and product of the result and 29 will also be an odd number
again, sum of two odd number is always an even number
so sum of 13 x 23 x 29 and 13 will be even number.greater than two
since even number greater than two are divisible by 2 and hence a composite number.
so 13 x 23 x 29 + 13 is a composite number
