Algebra.Com's Answer #326294 by richard1234(7193) You can put this solution on YOUR website! 4321 = 29*149, in which 140*141*...*160 is obviously divisible by 149, and it is also divisible by 29 because 145 is divisible by 29. Hence, the product 140*141*...*160 is divisible by 4321. \n" ); document.write( " |
