any multiple of 12
Since 2, 3 and 4 divide exactly into the number of rocks
We are looking for the common multiples of 2, 3 and 4
2 × 3 × 4 = 24 is possible but dividing by 2 gives 12 the lowest common multiple
Any multiple of 12 gives a possible number of rocks.
You are able to express numbers in like halves
