A warehouse has three shelves that can hold 8, 12, or 16 skateboards. Each shelf has sections holding the same number of skatebo

Aliun [14]

The greatest number of skateboards that can be stored would be the number that is the highest common factor of 8, 12, and 16

Factors of 8 = 1, 2, 4, 8
Factors of 12 = 1, 2, 3, 4, 6, 12
Factors of 16 = 1, 2, 4, 8, 16

The highest common factor = 4

Hence, the greatest numbers of skateboard that can be stored in each section is 4
