Composite numbers between 51 and 100 are 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, and 100
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.
51 is composite. 51 = 3 x 17. The other three numbers are prime numbers.
51 is a composite number. Its positive integer factors are 1, 3, 17, and 51.51 is not a prime number because it has more than two factors
41 is prime. 51 is composite. 51=3 x 17 . 71 is prime. 81 is composite. 92 91 is composite. 91 = 7 × 13
