A baker has 444 sweet biscuits and 276 salty biscuits. He wants to stack them in such a way that each stack has the same number and same type of biscuits and they take up the least area of the tray. What is the number of biscuits that can be placed in each stack for this purpose?
444 = 2*2*3*37
276 = 2*2*3*23
LCM of (444 and 276) = 2*2*3 = 12
thus, the no. of biscuits that can be placed in each stack for this purpose = 12
