is really the only way of checking which number is divisble by 7 is by modular arithematics?
loop quantum gravity said:can you tell me what hfc means?
loop quantum gravity said:and by modulo arithematics i mean that i divise the options of a number which is divisble by 7, and i got a blazing shock if ofcourse my way is right, it could be wrong.
shmoe it cannot be that hfc is the same as gcd, at least in a page where iv'e seen a proof that hfc(a,b)=hfc(a,a-b).

loop quantum gravity said:and about the test for divisibility, I'm not sure if it's genuine, but i welcome you if you can provide a link to these tests because i might as well just did something which is already known and not new at all.
Division by seven is a mathematical operation where a number is divided into equal groups of seven. It is represented by the symbol ÷ or by writing the dividend (number being divided) over the divisor (number of groups).
Modular arithmetic is a system of arithmetic where numbers "wrap around" after reaching a certain value, called the modulus. This means that after performing a calculation, the result is reduced to its remainder when divided by the modulus. For example, in modular arithmetic with a modulus of 7, 9 mod 7 would equal 2, as 9 divided by 7 has a remainder of 2.
Division by seven and modular arithmetic have various applications in mathematics, computer science, and other fields. They can be used to solve certain types of equations, calculate remainders, and create efficient algorithms. They also have connections to number theory and cryptography.
Most programming languages have built-in functions or operators for division and modular arithmetic. For division, the most common symbol is "/" or "div", and for modular arithmetic, "%" or "mod" are commonly used. It is important to check the syntax and rules for performing these operations in the specific programming language you are using.
One helpful tip is to remember the properties of modular arithmetic, such as the distributive and associative properties. It can also be useful to break down a problem into smaller steps and solve each step separately. Finally, practicing with different types of problems can improve understanding and problem-solving skills.
