2, 3, 5, 7, 11, 13, 17, 19 are all the primes between 1 to 20. 4, 6, 8, 9, 10, 12, 14, 15, 16 and 18 are all the composite numbers between 1 to 20.
So, M×N is 34 in ratio of Even numbers, and 14 ratio of Odd. If this equation is true, then non-prime numbers are only double-times of prime numbers. Please check my proof.
