Can a number be relatively prime to itself?
Two number are said to be "relatively prime" if they have no common factors - of course, other than the trivial factor 1. Even a prime number is not "relatively prime" to itself, since the prime number itself is the common factor. For example, the common factor of 7 and 7 is 7. Thus, the only situation I can think of where a number has no common factor with itself is that the number is 1.
What does group 7 have in common?
All elements in Group 7 have the same number of electrons in their outermost shell and this number corresponds to the group number.
List common multiples of the number 7?
Multiples of 7 include 7, 14, 21, 28 and so on. For them to be common, they need to be compared to another set of multiples.
What is the greatest common factor of 28 and another number is 7 The second number is between 60 and 70 What is it?
The GCF of 28 and 63 is 7.
What is the greatest common factor of 7 and 21?
The GCF of 7 and 21 is 7. Since 7 is a factor of 21, it is automatically the GCF.Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 7 are 1 and 7.The factors of 21 are 1, 3, 7, and 21..The common factors are 1 and 7. Therefore, the greatest common factor is 7.The GCF is 7.

Is the valency of an element same as its oxidation number?
Sometimes yes ... sometimes no. Valency of chlorine is 7 ... it has 7 valence electrons. But its most common oxidation number is -1.
