Qbasic program to find HCF of input two numbers

Introduction:

QBasic is a high-level programming language that is easy to learn and was popular in the 1980s and 1990s. It is a great choice for beginners who are just starting to learn programming. In this article, we will discuss how to write a QBasic program to find the HCF (Highest Common Factor) of input two numbers.

Before we dive into the program, let's first understand what HCF is. HCF is the largest positive integer that divides two or more numbers without leaving a remainder. For example, the HCF of 12 and 18 is 6, because 6 is the largest number that divides both 12 and 18 without leaving a remainder.

Qbasic coding for find the HCF of input two numbers.

CLS

INPUT "Enter first number:"; n1

INPUT "Enter second number:"; n2

IF n1 < n2 THEN

min = n1

ELSE

min = n2

END IF

i = 1

DO WHILE i <= min

IF (n1 MOD i = 0) AND (n2 MOD i = 0) THEN

hcf = i

END IF

i = i + 1

LOOP

PRINT "The HCF of"; n1; "and"; n2; "is"; hcf

END

Using SUB Procedure

DECLARE SUB hcf ()

CLS

CALL hcf

END

SUB hcf

INPUT "Enter first number:"; n1

INPUT "Enter second number:"; n2

IF n1 < n2 THEN

min = n1

ELSE

min = n2

END IF

i = 1

DO WHILE i <= min

IF (n1 MOD i = 0) AND (n2 MOD i = 0) THEN

h = i

END IF

i = i + 1

LOOP

PRINT "The HCF of"; n1; "and"; n2; "is"; h

END SUB

Using Function Procedure

DECLARE FUNCTION hcf (n1, n2)

CLS

INPUT "Enter first number:"; n1

INPUT "Enter second number:"; n2

PRINT "The HCF of"; n1; "and"; n2; "is:"; hcf(n1, n2)

END

FUNCTION hcf (n1, n2)

IF n1 < n2 THEN

min = n1

ELSE

min = n2

END IF

i = 1

DO WHILE i <= min

IF (n1 MOD i = 0) AND (n2 MOD i = 0) THEN

h = i

END IF

i = i + 1

LOOP

hcf = h

END FUNCTION

Output:

Conclusion:

In conclusion, QBasic is a simple and easy-to-learn programming language that can be used to write programs to solve various mathematical problems, including finding the HCF of two input numbers. The program we discussed in this article is a great example of how to write a QBasic program to find the HCF of input two numbers. By using this program as a starting point, beginners can learn the basics of programming and develop their skills in QBasic.
