5 x 31
All prime numbers are rational.
There is no need to do prime factorization as prime numbers are already prime.
All prime numbers are not odd numbers. 2 is an even prime number, and it is the only even prime number because all other even numbers have 2 as one of their factors.
It is impossible to list the infinite number of prime numbers and composite numbers.
5 x 31
155
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.
The prime factorization of 155 is 5 * 315x31
You need at least two numbers to find a GCF.
155 is not a prime number, so it can't be a prime factor.
Prime factors of 155 are 5 and 31
2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97 these are all the prime numbers
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.
All prime numbers are rational.
They are all odd, and they are all prime numbers
It is: 5*31 = 155
