3 x 17
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.
24, 51 and 72 are composite numbers 71 is a prime number.
The number 51 is a composite number because it has factors other than 1 and itself. Specifically, 51 can be divided evenly by 1, 3, 17, and 51. In contrast, prime numbers are only divisible by 1 and themselves.
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.
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 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.
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
No, 41, 51, 71, 81, and 91 are not prime numbers. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In this case, all the numbers listed can be divided by numbers other than 1 and themselves, making them composite numbers.
