Answer:

40 coins

Step-by-step explanation:

Note that

$10=\underline{2} \cdot 5,\\ \\8=\underline{2} \cdot 2\cdot 2.$

To find the least common multiple you have to multiply all common multiplies and then multiply them by all factors that left. Thus,

$LCM(10,8)=\underline{2} \cdot 5\cdot 2\cdot 2=40.$

This means that if Walt and Amy each have 40 coins, then Walt can make 4 stacks with 10 coins in each and Amy can make 5 stacks with 8 coins in each.
