Question 1:
73 is a prime number. It can only be divided by 1 and by itself.Â
The GCF of the three numbers:
 54                36               73
1×54              1×36              1×73
2×27              2×18
3×18              3×12
6×9               4×9
                  6×6
GCF of 54, 36 and 73 Â is 1
GCF of 54 and 36 is 18
If we divide 54 apples into 18 baskets, we have 3 apples in each basket
If we divide 36 oranges into 18 baskets, we have 2 oranges in each basket
If we divide 73 bananas into 18 baskets, we have 4 bananas in each basket + one banana left over.
So the greatest number of identical fruit baskets we can make with the least amount of fruit left over is 18 baskets
