155 is not a Prime number, hint: Any number ending in a 5 is divisible by 5.
155 is not a prime number, but a composite number, as it is divisible by 5 and 31.
155 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 4 factors of 155 are 1, 5, 31, and 155.The factor pairs of 155 are 1 x 155 and 5 x 31.The proper factors of 155 are 1, 5, and 31 or,if the definition you are using excludes 1, they are 5 and 31.The prime factors of 155 are 5 and 31.The 2 distinct prime factors (listing each prime factor only once) of 155 are 5 and 31.The prime factorization of 155 is 5 x 31.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.
neither prime or composite
It is prime

155 five is composite. It is composite because it has 5 as a factor. The only number that can be neither prime nor composite is 1.
155 is a composite number. Its factors are 1, 5, 31, and 155.
155 is not a prime number, but a composite number, as it is divisible by 5 and 31.
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 155 is composite.
not prime, since it is divideable by 5, and 31.
465 is a composite number. Its positive integer factors are: 1, 3, 5, 15, 31, 93, 155, 465
