Solve the problem.Euler conjectured that the formula n2 - n + 41 would generate prime numbers for whole numbers n. The formula generates prime numbers for n up to 40 and fails at n = 41. Evaluate Euler's formula for n = 42 and determine whether this is a prime number. If it is not a prime number, give its prime factors.
