body: <p>As we know 1000000007 is a large prime number.
  How can I find multiplication of two large numbers modulo 1000000007</p>
  
  <p>For example if I want to find 78627765*67527574 mod 1000000007, how can I do it.</p>
  
  <p>At least if anyone tell me the procedure I shall try</p>
  
  <p>Note: pls let me know the solution with primitive datatypes like int,long or long long
  Thanks in advance</p>
