and the next few ones:

30030, 510510, 9699690, 223092870, 6469693230, 200560490130, 7420738134810, 304250263527210, 13082761331670030, 614889782588491410, 32589158477190044730, 1922760350154212639070

Let’s take the product of the first primes and divide it by an integer in order to produce a palindrome

Starting with a few obvious solutions:

………. k = 210

…………….. k = 105

…………….. k = 70

…………….. k = 42

…………………… k = 35

…………….. k = 30

Note that

, and

The missing primes are 5 and 7, so

So we write,

Similarly,
