Is 98 a prime or composite number?

Answer

Number 98 is not a Prime

98 = 2 × 7²

98 has 6 divisors — 1, 2, 7, 14, 49 and 98; a prime has exactly two: 1 and itself.

Primes up to √98

9² = 81 ≤ 98 < 100 = 10², so it is enough to try primes up to 9

  • ÷2 divides

98 ÷ 2 = 49 — 2 divides 98, so 98 is composite

Nearest primes: 97 and 101
