There's no largest prime number. You can prove it by contradiction.
Suppose that there is a largest prime number, and the denote it by p_n, where p_n is the nth prime number (and the largest prime number). Then, let N denote the product of all the prime numbers, then
N = p_1 * p_2 * p_3 * ... p_n
N + 1 = p_1 * p_2 * p_3 * ... p_n + 1
Since (N + 1) is not divisible by any prime numbers, (N + 1) is also a prime number. Furthermore, knowing that N + 1 > p_n which contradicts that p_n is the largest prime.
Hence there's no largest prime number.

prime numbers have absolutely no pattern, equation, or formula. there is no way of finding the largest prime number. they go on forever.

Prime number is totally statistical phenomena, in statistics, the prime number is shown as 6n + 1 or 6n - 1, where n is natural number.
The first few primes are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 47, 53, . . .
U see the primes tend to infinite, so u are unable to call any prime as infinite.

there are infinite numbers in the world we can't take very larger number to calculate the prime number because if any number divided by itself if gives the remainder =1and by dividing by any other number gives remainder not equal to 0 then it is a prime number

there is no largest prime number. you can keep going higher because numbers are infinite.

Prime numbers are whole numbers only dividable by 1 and itself.
There is no "Largest"

a prime number is a number that can only he multiplied by itself to get...well, itself. Like 1x1=1 and 1x5=5 the longest prime number.....good luck finding tht
