3 answers

A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers, which means it has exactly two distinct positive divisors: 1 and itself.

Let's check each number:

  • 801: This number is not prime because it can be divided by 3 (801 = 3 × 267).
  • 141: This number is not prime because it can be divided by 3 (141 = 3 × 47).
  • 203: This number is not prime because it can be divided by 7 (203 = 7 × 29).
  • 139: This number is prime because it has no divisors other than 1 and 139.

Thus, the prime number in the list is 139.
