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!!
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
The Prime Factors are: 5 x 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.
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.
The prime factors of 55 are 5,11.
5 and 11
The first step in finding the factors of a number is to break it down into its prime factors. 55 is known from times tables to be 5x11, so we know its prime factorization is 5x11. To find any factors other than 1, you just multiply any combination of the prime factors together. In this case, 55 gives us the factors of: 1, 5, 11 and 55.
It is 55 because it has more than 2 factors
55 is a composite number because it has other factors aside from 1 and itself. The other factors of 55 are 5 and 11.
770. To find the least common multiple, factor each number to its prime factors and then multiply all the factors from the first number with any factors in the second number that are not repeated from the first number. The prime factors of 14 are 2 and 7. The prime factors of 55 are 5 and 11. Multiply 2 x 7 x 5 x 11 and you get 770.
