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 numbers are relatively prime, or co-prime.
The greatest common factor of two different prime numbers is 1. The two prime numbers have as their factors, 1 and themselves. That means that 1 is the only factor they have in common.The GCF is 1.
The greatest common factor of two or more prime numbers is 1.
No. Two numbers are relatively prime if they have no prime factors in common. Two even numbers will have 2 as a prime factor in common.
If the greatest common factor is 1, then the numbers are said to be co-prime or relatively prime.
The numbers are CO-prime, but not necessarily prime numbers: think of 3 and 4....
No, they have two: 1 and the prime number itself.
All prime numbers only have two factors, one and themselves.
One
Two
Any two different prime numbers are relatively prime because relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor.
