Sum of Numbers,Factorial,LCM

1.Sum of n numbers: FlowChart: JavaScript: let sum = 0 ; let num = 1 ; while ( num <= 10 ) { sum = sum + num ; num = num + 1 ; } console . log ( " Sum = " , sum ); Output: Java: public class Main { public static void main ( String [] args ) { int sum = 0 ; int num = 1 ; while ( num <= 10 ) { sum = sum + num ; num = num + 1 ; } System . out . println ( "Sum = " + sum ); } } Python: sum = 0 num = 1 while num <= 10 : sum = sum + num num = num + 1 print ( " Sum = " , sum ) 2.Factorial of n Numbers: FlowChart: Javascript: let fac = 1 ; let no = 1 ; while ( no <= 10 ) { fac = fac * no ; no = no + 1 ; } console . log ( " Factorial = " , fac ); Output: Java: public class Main { public static void main ( String [] args ) { int fac = 1 ; int no = 1 ; while ( no <= 10 ) { fac = fac * no ; no = no + 1 ; } System . out . println ( "Factorial = " + fac ); } } Python: fac = 1 no = 1 while no <= 5 : fac = fac * no no = no + 1 print ( " Factorial = " , fac ) 3.LCM(Least Common Multiple): Flowchart: Jav
