How many prime factorizations does every number have?
Every prime number has exactly 2 factors, 1 and the number itself.
Does every number have prime factorization?
Every number has at least one factor, the number 1.Every number greater than 1 has at least two factors, 1 and itself.Any number with exactly 2 factors is prime.Any number with more than 2 factors is composite; in this case it can be factorised completely into primes.The number 1 has only one factor. It is therefore neither prime nor composite.
Is 2468 a prime number?
2468 is not a prime number because it has more than twofactors.Points to remember!1-Every number except 0 is divisible by itself.2-Every number is divisible by 1.3-It means every number except 0 and 1 has minimum two factors.Therefore, 2468 has factors: 1 and 2468.In order to show that given number is not prime there is no need to find all the factors we just have to show that it has more than two factors.2468 is also divisible by 2, which means that 2 is also a factor of 2468(more than two factors).Therefore, 2468 is not a prime number.
