2 x 5 x 5 = 50
2 x 5 x 7 = 70
50 is not prime. The only even prime number is 2. 1 is a common factor to all integers so every list of factors will start with 1.
... 47, 53, 59 ... As you can see there is no Prime Number 50 in the partial list to the left, unless it is 53?
1, 11, 21, 31, 41. 1 is not a prime number.
That's an infinite list.
There are an infinite number of prime numbers. It is, therefore, not possible to list those above 50.
A single number cannot be relatively prime. Any pair of numbers between 50 and 100 of which one is a prime will be relatively prime. There are 728 pairs of numbers that are relatively prime and I have neither the time nor patience to list them all!
53,59,61,67,69,71,73.
All the prime numbers between 50 and 75 are: 53, 59, 61, 67, 71 and 73.
The next prime number after 50 (which is not prime) is 53.
41, 43, 47
The first prime number after 50 is 53.
The first prime number after 50 is 53.
