It is composite.
361 is not prime. 361 = 19 * 19
All composite.
361 is a multiple of 19.
They are: 19*19 = 361 or as 192 = 361
361 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 3 factors of 361 are 1, 19, and 361. Because 361 is a square number (19 x 19), there are an odd number of factors.The factor pairs of 361 are 1 x 361 and 19 x 19.The proper factors of 361 are 1 and 19 or,if the definition you are using excludes 1, there is only 19.The prime factors of 361 are 19 and 19. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The distinct prime factor (listing each prime factor only once) of 361 is 19.The prime factorization of 361 is 19 x 19 or, in exponential form, 192.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
19 x 19 = 361

4, composite. 67, prime.
You can't simplify that. The only prime factors in 500 are 2 and 5 - and neither of them is a prime factor of 361.
