find the smallest number of six digits exactly divisible by 25 , 35,45 and 15 .
"smallest number of six digits is 100000 . required number must be divisible by l . c . m . of 25,35 , 45,15 i . e 1575 , on dividing 100000 by 1575 , we get 800 as remainder . therefore , required number = 100000 + ( 1575 â € “ 800 ) = 100775 . answer is b ."
add(subtract(multiply(const_10, multiply(const_100, const_100)), const_100), 35,45)
