the least number by which 72 must be multiplied in order to produce a multiple of 112 , is :
required number is divisible by 72 as well as by 112 , if it is divisible by their lcm , which is 1008 . now , 1008 when divided by 72 , gives quotient = 14 . therefore , required number = 14 . answer : c
divide(112, gcd(72, 112))
