What is the remainder when the square of any prime number greater than 3 is divided by 3?
Any prime number greater than 3 is of the form 6 k ± 1 , where k is a natural number. When, 6 k ( 6 k ± 2 ) + 1 is divided by 6, we get, k ( 6 k ± 2 ) and remainder as 1. Hence, the correct choice is (a).
What is the remainder when the square of prime number greater than 3 is divided by 6 is?
1
∴ When the square of any prime number greater than 3 is divided by 6, the remainder is 1.
What do you notice about the locations of the prime numbers greater than 3?
We have shown that every prime greater than 3 is located in either the fourth or sixth columns of our grid. This means that it is necessary for the number to be located in one of those two columns if it is prime and greater than 3.
What happens when you square a prime number?
In mathematics, a semiprime is a natural number that is the product of exactly two prime numbers. The two primes in the product may equal each other, so the semiprimes include the squares of prime numbers. Because there are infinitely many prime numbers, there are also infinitely many semiprimes.
What is the remainder when a square number is divided by 3?
The remainder of a perfect square when divided by 3, is either 0 or 1 but never 2.
What is the remainder when a square number is divided by 4?
∴ The remainder is either 0 or 1 when the square of any number is divided by 4.
How do you find the next prime number?
There is no formula on how to find the next prime number. dCode uses an algorithm that performs a probabilistic primality test (Miller-Rabin test) on each of the numbers greater than or equal to the number requested, then check it with a deterministic test. Example: The first prime number following 1000 is 1009 .

Are there any Even prime besides 2?
Two is a prime because it is divisible by only two and one. All the other even numbers are not prime because they are all divisible by two.
Is 3 a perfect square and divisible by 3?
It is zero when the base number (a in case of a^2) is divisible by 3. For all other numbers, the square when divided by 3, the remainder is always 1. When the number is divisible by 3, the remainder is obviously going to be zero. Let’s say the number is not divisible by 3.
Is the remainder obtained when a perfect square is divided by 3 What is the value of p?
Hence, the remainder obtained when a perfect square is divided by 3 is either 0 or 1.
Is every prime number greater than 3 divisible by 6?
Show that any prime number greater than 3 has remainder 1 or 5 when divided by 6; Every prime number greater than 3 is odd and not divisible by 3.
How do you find the remainder of a prime number?
So if n is prime, then the remainder r is either 1 (and n = 6 q + 1 is one more than a multiple of six), or 5 (and n = 6 q + 5 = 6 ( q +1) – 1 is one less than a multiple of six). Remember that being one more or less than a multiple of six does not make a number prime.
What are some of the most rediscovered results about prime numbers?
Perhaps the most rediscovered result about primes numbers is the following: I found that every prime number over 3 lies next to a number divisible by six. Using Matlab with the help of a friend, we wrote a program to test this theory and found that at least within the first 1,000,000 primes this holds true.
How many strange numbers are there in prime numbers?
Every one digit prime number is strange and a number of two or more digits is strange if and only if so are the two numbers obtained from it by omitting either. . . . The number 12 = 2^2 × 3 has 6 factors. What is the smallest natural number with exactly 36 factors?
