It is 55 because it has more than 2 factors
55 does not have 3 prime factors.
55 does not have 3 prime factors.
The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
3 is a prime number. Its only prime factor is 3.
3 is a prime number.4 is not a prime number. It is a composite number.
3 is a prime number.
55 3*55 = 165 2*55 = 110
3 is a prime number
3 is a prime number. Any number that only has itself and one as factors is a prime number. Therefore, since there are no factors of 3 other than one and itself it is a prime number.
The greatest common factor of 45 and 55 is 5 To determine GCF you first find the prime factors of each number. For 45 this is (5, 3, 3). For 55 this is (11, 5). Then you take the product of the prime factors that they have in common. In this case the only prime factor they have in common is 5 so the answer is just 5. For a better illustration of the rule look at 45 and 30. Prime factors of 45 are (5, 3, 3) Prime factors of 30 are (5, 3, 2) The prime factors in common are 5 and 3 and the product of these numbers is 15. Therefore the GCF of 45 and 30 is 15.
3 is a prime number because its only factors are 1 and 3. A prime number is a number that's factors are 1 and itself.
