The median for the first 20 prime numbers would be 30. This is because the middle two numbers of the first 20 prime numbers are 29 and 31. To find the median from this, we need to find the average of these two numbers. This is 30.
No two prime numbers can make 30.No two prime numbers can make 30.No two prime numbers can make 30.No two prime numbers can make 30.
31 37
They are: 23 and 29
Prime numbers between 30-50= 31, 37, 41, 43, 47
The factors of 30 that are not prime numbers are 6, 10 and 30.
The question does not make sense since 20 and 30 are not prime numbers!
23 and 29
2 x 3 x 5 = 30
29 is a prime number. There are no prime numbers between 29 and 30.
The greatest factor of a set of numbers is the greatest number in the set. It will be a factor of itself. It will not be a factor of the other numbers in the set but that is not what the question requires.To find the greatest COMMON factor, find the prime factorisation of each number.Multiply together each prime factor raised to the lowest power is any of the numbers.That product is the greatest common factor.
The prime numbers between 30 and 50 are 31,43,39,41, and 47
