Is the sum of any two prime numbers always a composite number?
The sum of any two prime numbers is not always a composite number. The sum of 2 and 11 is 13, and 13 is a prime number, not a composite number.
Is 1099 a prime number or a composite number?
Solution: 1099 is a prime number.
Is a composite number times a composite number always composite?
Yes. To be composite, the first number has at least 2 prime factors, the second number also has at least prime factors; the product of the two will have at least 4 prime factors, so it must be a composite number.
In math what is a prime number?
in math a prime number is a number with only 2 factors. the factors are the number 1 and the number itself. 1 is not a prime number nor composite. 2 is a prime number because its only factors are 2 and 1. any other even number will be composite because 2 and some other number will always equal an even number.
When is product of 2 prime numbers a prime number?
The product of two prime numbers is always a composite number, and it never is a prime number.
Is the sum of a prime number and a composite number always even?
No, the sum of a prime number and a composite number is not always even.
What is the least common multiple of 20 and 41?
LCM of a prime number and a composite number is always equal to their product if the composite number is not a multiple of the prime number. Here, 41 is a prime number and 20 is a composite number. Therefore LCM(20,41) = 20 x 41 = 820
Is the sum of any two prime numbers always a composite number?
The sum of any two prime numbers is not always a composite number. The sum of 2 and 11 is 13, and 13 is a prime number, not a composite number.
When you multiply a prime and a composite number do you always get a composite number?
Product of a prime number and a composite number results in a composite number.Now consider the product of a composite number(a) and a prime number(b) is equal to c.i.e. c = a x bIt is clear that c is divisible by both a and b.Also c is divisible by itself and 1, this means that c has more than two factors.A number having more than two factors is composite, therefore product of a prime number and a composite number results in a composite number.
