find the greatest number which on dividing 1255 and 1490 , leaves a reminder of 8 and 11 respectively
"explanation : in this type of question , its obvious we need to calculate the hcf , trick is hcf of ( 1255 - 8 ) and ( 1490 - 11 ) = hcf ( 1247 , 1479 ) = 29 option b"
gcd(subtract(1255, 8), subtract(1490, 11))
