You need at least two numbers to find a GCF.
Prime factor each number and choose the common factors to multiply.85=5x17155=5x315 is the greatest common factor.
1, 5, 31, 155 5 x 31 = 155
5 x 31 = 1557 x 31 = 217The GCF is 31.
35 can be a factor, but it is not prime.
The prime factorization of 155 is 5 * 315x31
The prime factors of 150 are 2, 3, 5 and 5 The prime factors of 155 are 5 and 31. The only, and therefore the greatest, common factor is 5
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.
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.
* The prime factors of 55 are 5 and 11. * The prime factors of 155 are 5 and 31. Therefore the only common factor betwen them is 5. So it is also the highest.5.The GCF is 5.
12 is not a factor of 155. The factors of 155 are 1, 5. 31 and 155.
Since the numerator of the fraction is prime, and is not a factor of the denominator, the proper fraction 53/155 is already expressed in simplest form.
Prime factors of 155 are 5 and 31
3 x 5 = 155 x 5 = 25The GCF is 5.
You need at least two numbers to find a GCF.
It is: 5*31 = 155
Prime factor each number and choose the common factors to multiply.85=5x17155=5x315 is the greatest common factor.
