Important Tips

  • Number of divisors for given number N is   given by the relation explained below (when a,b,c are prime)

 

Then number of divisors = (X+1) (Y+1)(Z+1)

 

  • The remainder obtained by the method of successive division is called complete remainder. It is given by the formula

Complete Remainder= R1+D1 x R2+D1xD2xR3+………………………….
