To celebrate the first day of winter, Lin is putting magnets on some of the lockers (pre-CO VID of course). There are 100 lockers along one side of her school's hallway. She puts a snowflake magnet on every 5th locker and a snowman magnet on every 7th locker. Is this a GCF or an LCM question?

Answer :

This will be a LCM because there is no GCF between the 5th lockers and 7th lockers.
I’m almost 97% sure this would be LCM
