The Newport Crab Company marks the location of its crab pots with colored balloons. They mark every fourth pot with a red balloon, every sixth pot with a blue balloon, and every tenth pot with a yellow balloon. After placing 600 crab pots in the bay, how many pots have three different colored balloons attached?

LCM of 4 6 and 10 is     60    so every 60th crab pot has 3 balloons    600/60 = 10
