No Prime number can equal 13, 5, 31, 7, 53 and etc.
Never. 1 is not a prime number.
It is always 1 and the prime number itself.
Yes, a prime number is always greater than 1.
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.
1+1=2
1 itself, 1 raised to any power will always equal 1
Yes, it is always. Assume temporarily that the product of two prime numbers is not always composite. This implies that that at least one product of prime numbers is also prime. Now, say two different prime numbers p and q, when multiplied, equal r. If r is a prime number, then r's only positive factors are 1 and r. But 1 is not a prime number. This contradicts that both p and q are prime (because either p or q MUST be 1). Therefore, the product of two prime numbers is always composite.
The 7th Mersenne prime is equal to 2^19-1
GCF of a composite number and a prime number is always 1. Here, 5 is a prime number therefore, gcf is 1.
31 is a prime number. Its only factors are 1 and 31. But technically, ' 1 ' is not considered a prime number, so, technically, there is no answer to this question.
Yes.
No prime numbers equal 84. The only number equal to 84 is 84,and it isn't a prime number.The prime factors of 84 are: 1, 2, 2, 3, and 7
