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
To find the least common multiple (LCM) of 44, 55, and 66, we first need to find the prime factorization of each number. The prime factorization of 44 is 2^2 * 11, the prime factorization of 55 is 5 * 11, and the prime factorization of 66 is 2 * 3 * 11. To find the LCM, we take the highest power of each prime factor that appears in any of the factorizations, so the LCM of 44, 55, and 66 is 2^2 * 3 * 5 * 11, which equals 660.
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.
