Algebra.Com's Answer #660031 by robertb(5830) You can put this solution on YOUR website! We can brute-force our way to a solution:\r \n" ); document.write( "\n" ); document.write( "1 modulo 2 ===> 1,3,5,7,9,11,13,15,17,19,21,23,25,27,29, 31 \n" ); document.write( "1 modulo 3 ===> 1,4,7,10,13,16,19,22,25,28,31 \n" ); document.write( "1 modulo 5 ===> 1,6,11,16,21,26,31\r \n" ); document.write( "\n" ); document.write( "Barring the possibility that there is only one egg, the least number of eggs for this grouping to be done is 31.\r \n" ); document.write( "\n" ); document.write( "(There is a conventional method of doing this problem, by means of the chinese remainder theorem, but the \n" ); document.write( "solution above should suffice.) \n" ); document.write( " \n" ); document.write( " |
