<p>Students should keep repeating the divisibility process until they reach a small number that confirms divisibility by 80. For example: Check if 5760 is divisible by 80 using the divisibility test. Divide the last two digits by 4: 60 ÷ 4 = 15. Since 15 is not a multiple of 20, 5760 is not divisible by 80.</p>
