55 is not a prime number because you can do 5*11=55. The definition of a prime number is a number that has only the factors of 1 and itself. Because 55 has 1*55-55 AND 5*11=55 it is not a prime number. Hope that helps!!
59 is the first prime number after 55.
67 is the greatest prime number between 55 and 70
-55
The Prime Factors are: 5 x 11

59 is the first prime number after 55.
The odd composite numbers between 50 and 60 are 51, 55, and 57. Because all the primes are odd except for 2 and adding two odd numbers will result in an even number, one of the two prime numbers must be 2, which when added to an odd number will result in an odd number. So, we subtract 2 from each of these numbers and check whether it is prime. 51 - 2 = 49, which is not prime. 55 - 2 = 53, which is prime. 57 - 2 = 55, which is not prime. Thus, the number is 55, which can be written as 2 + 53.
67 is the greatest prime number between 55 and 70
55 = 5 * 11

To find the prime factorization of a number, start with any factor pair of that number and keep factoring the composite numbers until all factors are prime. 55 5 x 11 = 55 Both factors are prime, so that is the prime factorization.
The Prime Factors are: 5 x 11
1,5,11,55 and it is a prime number
Prime factorization means to change a composite number into the product of its prime factors as for example 55 as a product of its prime factors is 5*11 = 55
71 is prime. 55 is not a prime number. Its positive integer factors are 11 and 5. The number 71, meanwhile, is prime, as it has no positive integer factors other than itself and 1.
