Question 447144: Let the "kernel" of a number be defined as the square of its greatest prime factor. For instance,the "kernel" of 18 is 9, because the greatest prime factor of 18 is 3(prime factorization: 18=2*3*3), and =9.
What is "kernel" of 39?

You can put this solution on YOUR website!
well, start with the prime factorization of 39
39=3*13
of these prime factors, 13 is the largest, therefore the kernel (under your definition) is 13^2 which is 169
