91 is the only composite factor of 91. 7 and 13 are prime.
91 = 7 x 13
A person unfamiliar with prime numbers could mistake 51, 91, or any other composite number for a prime number if the person did not factor the number to make sure it had no other factors then 1 and itself.
They are: 7 times 13 = 91
Prime numbers have one distinct prime factor.
91 is the only composite factor of 91. 7 and 13 are prime.
91 = 7 x 13
To identify the GCF of 91 and 78, you first need to break these down into their prime factors: 91 = 7x13 78 = 2x3x13 The next step is to identify any common prime factors. In this case, both numbers have 13 as a prime factor. Thus the greatest common factor of 91 and 78 is 13.

No.
You want to factor (x4 -91) First notice that the factors of 91 are 1, 7, 13, and 91. If we try them all , we see that x4 -91 is a prime polynomial. Even though the polynomial is prime, that is cannot be factored over the set of rational numbers, it is factorable over the set of irrational numbers. x4 - 91 = (x2)2 - (√91)2 = (x2 - √91)(x2 + √91) = [x2 - (√√91)2](x2 + √91) = (x - √√91)(x + √√91)(x2 + √91)
97 is prime.
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
7
