Answer :
Final answer:
To verify if a number is prime, you need to check its divisibility by all prime numbers up to its square root. In case of 139, this includes 2, 3, 5, 7, 11 and 13. Since 139 isn't divisible by any of these, it is a prime number.
Explanation:
The statement is false. While it's true that if a number is not divisible by 2, 3, 5, 7, or 11 then it couldn't be a multiple of these numbers, these are not the only numbers you need to check to confirm if a number is prime. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. To verify whether 139 or any number is a prime, you would need to check its divisibility up to its square root. The square root of 139 is approximately 11.79. Therefore, you would need to check divisibility by all prime numbers less than or equal to 11.79, which includes 2, 3, 5, 7, and 11 as stated, but also includes 13. Since 139 isn't divisible by any of these numbers, it is indeed a prime number.
