18 is not a prime number so no number can have 18 as a prime factor.
Prime numbers have one distinct prime factor.
Not a lot. They're both prime numbers. A factor that is prime is used to make other numbers.
No, 12 and 18 are not coprime. Their common factors are 2, 3, and 6.
To find the GCF of 18 and 10 you have to split them into their prime factors: 18 = 2x3x3 10 = 2x5 Next you have to identify any common prime factors. In this case both numbers have a 2 as a prime factor. Therefore, the GCF of 18 and 10 is 2.
18 is not a prime number so no number can have 18 as a prime factor.
Use a factor tree. 18 9,2 3,3,2
The common prime factors of 18 and 30 are 2 and 3.
The greatest prime factor of both numbers is 3
3
The GCF of 18 and 49 is 1. These numbers are relatively prime
A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
The 3 number that make the prime factorization of 18 are 2 x 3 x 3.
1 is a factor of 18; neither 1 nor 18 is prime.
Relatively Prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
All prime numbers have a common factor of 1.
