find the greatest number that will divide 54 , 87 and 172 so as to leave the same remainder in each case
explanation : required number = ( 87 - 54 ) , ( 172 - 87 ) , ( 172 - 54 ) = h . c . f of 33,85 and 118 is 1 answer : option d
gcd(gcd(subtract(subtract(172, 87), 54), subtract(87, 54)), subtract(172, 87))
