61 is a prime number
51 is a composite number but 61 is a prime number
ANSWER: 61 is a prime number but 51 is a composite number.61 is a prime number because the factors of 61 are 1 and itself (61).51 is a composite number because the factors of 51 other 1 and itself (51) are 3 and 17.
61 and 71 are prime numbers the rest are composite numbers
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.
33 = 3 x 11 51 = 3 x 17 41 prime 61 prime
3 x 17 = 51. It has factors other than 1 and itself. It is composite. 61 is prime. Its only factors are 1 and 61. 71 is prime. Its only factors are 1 and 71. 7 x 13 = 91. It is a composite number.
29, 61, 23, 97, 41, and 67 are prime. 81, 51, 93, 77, and 39 are composite.
61 is prime.

61 is prime.
51 is composite.
51 is composite. Becasuse 17 x 3 = 51 It is two prime numbers multiplied together to make a composite.
