It's unusual to describe the numbers 19 and 22 as "weird" in standard mathematical terminology. Numbers are typically categorized as prime, composite, even, odd, perfect, etc. Weird numbers, are actually a thing in mathematics but, neither 19 nor 22 qualify.
19: This is a Prime Number. It is only divisible by 1 and itself.
22: This is a Composite Number. Its divisors include 1, 2, 11, and 22. It is also an Even Number, meaning it is divisible by 2.
The term "weird number" has a very specific mathematical definition; it means that the sum of the proper divisors of the number (divisors excluding the number itself) exceeds the number, but no subset of those proper divisors sums to the number itself.
