  Given number = 2800

  using prime factorization
  

  2800=2×2×2×2×5×5×7
  

  if above number is multiplied by 7 then it will be perfect square.
  

  2800×7=19600 <b style=”background-color: var(–bb-content-background-color); font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>& root 19600​=140
