No Prime number greater than 2 has 2 as a factor. A prime number has only two factors, 1 and the number itself. All prime numbers have 1 as a common factor. Numbers with any number besides 1 as common factors are composite numbers.

When will the product of given numbers be greater than the LCM of the same given numbers?
When the numbers have a common factor (other than 1).
Are 39 and 45 relatively prime?
39 and 45 are not relatively prime because they have 3 as a common factor. Relatively prime numbers have no common factor greater than 1.
When is the LCM of 2 numbers less than their product?
When they have a common prime factor. When their GCF is greater than 1.
Which are the prime numbers with 1 as the common factor?
All prime numbers have a common factor of 1.
When is the LCM of two numbers neither of the numbers?
When their GCF is greater than 1. When they have a prime factor in common.
What is a common prime factor?
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.
What is the LCM of two numbers that have no common factor greater than 1?
If the HCF (Highest Common Factor) of two numbers is 1, then the two numbers are relatively prime and their LCM is the product of the two numbers.
When is the LCM neither the product of the two numbers?
When the GCF is greater than 1. When they have a prime factor in common.
What is common prime factors?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.
Is 21 and 35 relatively prime?
You need to check whether they have a common factor. You can simply factor each of the numbers; for numbers that are much larger, using Euclid's algorithm is much faster.If the common factor of two numbers is greater than 1, then they are NOT relatively prime.
What is the common factor of co-prime number?
Co-prime numbers have a common factor of 1.
If the greatest common factor of two numbers is one what can you say about the number?
The numbers are relatively prime, or co-prime.
