1 is not a Prime number (or composite).
The prime numbers from 1 to 11 are 2, 3, 5, 7, and 11.
They are all odd, and they are all prime numbers
The sum of all prime numbers between 1 and 11 is 28.
The numbers 11, 13, 17 and 19 are prime.
They are 2 and 11
12
The quoted numbers are all PRIME Numbers. The next prime numbers after '11' are , 13 ,17,19,23,29,31,37,41,43,47, up to '50' Prime Numbers , like ordinary numbers, go to infinity. NB After '2' , there are no. even prime numbers. They are all ODD NUmbers.
all the numbers are prime numbers therefore the prime factorization of 2*2*5*11=2*2*5*11
The LCM of two numbers is the product of the numbers if one of the numbers is a prime. Since 11 is a prime, the LCM of 10 and 11 is 110 (10 x 11). If neither number had been a prime, the LCM would have been the product of all the prime factors of the numbers to their greatest power.
Themselves because they are all prime numbers
No. All prime numbers are deficient.
There is only one of them and it is 11
