Any two Numbers from the keyboard, calculate the number of the two greatest common divisor and least-CodePudding

# include
Int main ()
{
Int a, b, c, I;
Printf (" please enter the number two \ n ");
The scanf (" % d % d ", & amp; A, & amp; B);
If (a{
C=a,
A=b,
B=c.
}
For (I=b; I> 0; I -)
{
If (a % I==0 & amp; & B % I==0)
Printf (" the greatest common divisor: % d \ n ", I);
}
C=a * b;
C=c/I;
Printf (" LCM % d \ n ", c);
return 0;
}

CodePudding user response:

Modified as follows, for your reference:

 # include & lt; stdio.h> 
Int main (int arg c, char * argv []) 
{
Int a, b, c, I, y. 
Printf (" please enter the number two \ n "); 
The scanf (" % d % d ", & amp; A, & amp; B); 
If (a{
C=a;//this is ";" , not ", "
 no.A=b; 
B=c. 
} 
for(i=1; i<=b; I++) 
{
If (a % I==0 & amp; & B % I==0) y=I;//add a variable y, and record the common factor 
} 
Printf (" the greatest common divisor: % d \ n ", y); 
C=a * b; 
C=c/y; 
Printf (" LCM: % d \ n ", c); 
return 0; 
}

CodePudding user response:

The cause of the error is in the greatest common divisor, I value to 0,

 c=c/I;

Will be an error,
Change the method

 for (I=b; I> 0; I -) 
{
If (a % I==0 & amp; & B % I==0) 
{//-- -- -- -- -- -- -- add -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
Printf (" the greatest common divisor: % d \ n ", I); 
break;//-- -- -- -- -- - after get the greatest common divisor, end the for loop -- -- -- -- -- -- -- -- -- -- 
}//-- -- -- -- -- -- -- -- -- -- - add -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
}
