Is 889 a prime or composite number?

Answer

Number 889 is not a Prime

889 = 7 × 127

889 has 4 divisors — 1, 7, 127 and 889; a prime has exactly two: 1 and itself.

Primes up to √889

29² = 841 ≤ 889 < 900 = 30², so it is enough to try primes up to 29

÷2 does not divide
÷3 does not divide
÷5 does not divide
÷7 divides

889 ÷ 7 = 127 — 7 divides 889, so 889 is composite

Nearest primes: 887 and 907
