The GCF of two or more numbers represents the largest number that will divide into the two or more numbers evenly with no remainder. 2 is the GCF of 4 and 6.
That would be called a "common factor" of the two (or more) numbers.
Numbers with two factors are called prime. Numbers with more than two factors are called composite.
Prime numbers have two factors. Composite numbers have more than two.
Try dividing by some numbers. The larger the number, the more numbers you have to divide by. It is enough to test division by 2, and all the odd numbers up to the square root of the number. For very large numbers, this is not efficient. There are more efficient methods, but they are also more difficult to understand.
A number that is a factor of two or more numbers is simply a common factor
A whole number that is a factor of two or more numbers is a common factor.
A composite number is the product of two or more prime numbers. A prime number has exactly two factors, 1 and the number itself; a composite number has at least one more factor than the two that a prime number has.
Prime numbers have two factors. Composite numbers have more than two.
A number that is a multiple oof two or numbers is called a common multiple
The smallest number that is a multiple of two or more numbers is called the least common multiple, or LCM.
Prime numbers have two and only two factors. Composite numbers have three or more.
The range of two numbers, or a set of numbers (more than two numbers) is the difference between the greatest number and the smallest number (numerically). Hope this helps!
Every number except the number 1 has at least two factors, 1 and the number itself. Prime numbers have exactly two factors and composite numbers have more than two factors. All even numbers except the number 2 are composite numbers and have more than two factors. The number 2 is prime and its only factors are 1 and 2.

Numbers with two factors are called prime. Numbers with more than two factors are called composite.
A prime number has only two factors, one and the number itself. A composite number has more than two factors.
