51 is composite (3 x !7); the other numbers are primes.
24, 51 and 72 are composite numbers 71 is a prime number.
Composite numbers are numbers that are not prime- that is, they are divisible by numbers besides 1 and themselves. 51 is actually divisible by 1, 3, 17, and 51, so it is composite.
51 is composite.
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.
3929 is a prime number and 51 is a composite number
51 is composite (3 x !7); the other numbers are primes.
51 is composite. Becasuse 17 x 3 = 51 It is two prime numbers multiplied together to make a composite.
24, 51 and 72 are composite numbers 71 is a prime number.
51 is a composite number. Composite numbers are any number that has more than two factors(one and itself). Therefore, since 3 and 17 are factors of 51 that makes it a composite number.
51 is divisible by 3, therefor it is composite. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1, 2, and 0. 1, 2, and 0 have a different name.
Composite numbers are numbers that are not prime- that is, they are divisible by numbers besides 1 and themselves. 51 is actually divisible by 1, 3, 17, and 51, so it is composite.
A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. In this case, the number 51 is a composite number because it has divisors other than 1 and itself, such as 3 and 17. Numbers 31, 41, and 61 are all prime numbers, as they only have two distinct positive divisors, 1 and the number itself.
51 is composite.
No
both are composite numbers 51 is divisible by 1,3,17,51 and 91 by 1,7,13,91
Just 51
