You don't have to test anything. Any number greater than 5 that ends in 5 is composite.
You only need to test numbers up to the last prime number equal to or less than the square root of a number when testing whether it is prime. The square root of 854 is between 29 and 30, so you would test up to the prime number 29.
It is 149 because as a product of its prime factors: 7*149 = 1043
To determine whether 1548 is prime, you only need to consider prime numbers up to the square root of 1548. The square root of 1548 is approximately 39.3, so the greatest prime to test is 37. The prime numbers to consider are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37.
8243 is a prime number, but there is no greatest prime number.

What is the greatest prime you must consider to test whether 2834 is prime?
You don't have to test anything. Any number greater than 5 that ends in 5 is composite.
To determine if 6437 is prime, you only need to test prime numbers up to the square root of 6437, which is approximately 80.2. Therefore, the greatest prime number you must consider testing is 79. If 6437 is not divisible by any prime numbers up to 79, then it is a prime number.
You only need to test numbers up to the last prime number equal to or less than the square root of a number when testing whether it is prime. The square root of 854 is between 29 and 30, so you would test up to the prime number 29.
It is 149 because as a product of its prime factors: 7*149 = 1043
There is no greatest prime number.
8243 is a prime number, but there is no greatest prime number.
13 is the greatest prime that needs to be checked to determine if 231 is a prime.
2 is a prime number because it is only divisible by 1 and itself.Ex:1*2=2It is the only even prime number and the smallest prime number!Yes and 2 is the only even prime number
you would need to look at all numbers up to square root of n, which in this case is 75.
The greatest prime number of 5141 is 71.
