Try dividing it by 5....
85 is a composite number because it has factors other than 1 and itself.The 4 factors of 85 are 1, 5, 17, and 85.The factor pairs of 85 are 1 x 85 and 5 x 17.The proper factors of 85 are 1, 5, and 17 or,if the definition you are using excludes 1, they are 5 and 17.The prime factors of 85 are 5 and 17.The distinct prime factors of 85 are also 5 and 17, since there is no repetition of factors.The prime factorization of 85 is 5 x 17.5 and 17 (both prime)85 = 5 x 17
it is composite.
