361 is not prime. It is divisible by 19.
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
neither prime or composite

It would be impossible to list them all, since numbers go on forever, but here are some of them: 2 - Prime 3 - Prime 4 - Composite 5 - Prime 6 - Composite 7 - Prime 8 - Composite 9 - Composite 10 - Composite 11 - Prime 12 - Composite 13 - Prime 14 - Composite 15 - Composite 16 - Composite 17 - Prime 18 - Composite 19 - Prime 20 - Composite 21 - Composite 22 - Composite 23 - Prime 24 - Composite 25 - Composite 26 - Composite 27 - Composite 28 - Composite 29 - Prime 30 - Composite 31 - Prime 32 - Composite 33 - Composite 34 - Composite 35 - Composite 36 - Composite 37 - Prime 38 - Composite 39 - Composite 40 - Composite 41 - Prime 42 - Composite 43 - Prime 44 - Composite 45 - Composite 46 - Composite 47 - Prime 48 - Composite 49 - Composite 50 - Composite
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.
