What is the greatest prime you must consider to test whether 2834 isβ prime?
There is no greatest prime number.
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.
All even numbers are composite except 2 itself which is a prime number because it has only two factors which are itself and one.

What is the greatest prime you must consider to test whether 2834 isβ prime?
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.
If its divisible by 2 then it's not a prime number. But 2 by itself is a prime number
It is 157 because the prime factors of 6437 are 41 and 157
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.
