5. When 147 is divided by N the remainder is 4
When 255 is divided by N the remainder is 8
When 622 is divided by N the remainder is 11
Find N?

• ans 13
  substract the rem from given nos
  i.e.
  147-4=143;255-8=247;622-11=611
  now find HCF of the obtained nos
  u will get 13

• 147 is divided by N,remainder is 4.So, 147-4=143 is divided by N.
  255 is divided by N,remainder is 8.So,255-8=247 is divided by N.
  622 when divided by N,remainder is 11.So,622-11=611 is divided by N.
  
  143=11*13
  247=13*19
  611=13*47
  
  Commojn multilple=13.So,N=13.

• dividend=divisor x quotient + remainder
  substract the remainder from dividend,
  i.e.
  147-4=143;255-8=247;622-11=611
  HCF of 143, 247,611=13
  Answer =13.
