80 has 5 factor pairs.
A whole number that is a factor of two or more numbers is a common factor.
YES.If k is even then 2 is a factor of k.If 5 is also a factor of k then 2 x 5 = 10 is another factor of k.NOTE : The product of two or more prime factors of a number produces another factor.
a common factor
A common factor.
80 has 5 factor pairs.
Any number is a factor and a multiple of itself. Other factors are less than the number, other multiples are more. 5 is a factor of 10. 10 is a multiple of 5.
The only number that's neither more nor less than 50 is 50.

Relatively Primenumbers 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.
A number that is a factor of two or more numbers is simply a common factor
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.
That is actually impossible. This is because every number has two factors ( the number itslef and 1) . If a number is even there will be one more factor, that is 2. So an even number has to have atleast 3 factors.
