6 <p><strong>Step 1:</strong>Check divisibility by 5. A number is divisible by 5 if its last digit is 0 or 5. In 320, the last digit is 0, so 320 is divisible by 5.</p>
6 <p><strong>Step 1:</strong>Check divisibility by 5. A number is divisible by 5 if its last digit is 0 or 5. In 320, the last digit is 0, so 320 is divisible by 5.</p>
7 <p><strong>Step 2:</strong>Check divisibility by 8. A number is divisible by 8 if the last three digits form a number that is divisible by 8. In 320, the last three digits form the number 320, which is divisible by 8 (320 ÷ 8 = 40).</p>
7 <p><strong>Step 2:</strong>Check divisibility by 8. A number is divisible by 8 if the last three digits form a number that is divisible by 8. In 320, the last three digits form the number 320, which is divisible by 8 (320 ÷ 8 = 40).</p>
8 <p><strong>Step 3:</strong>Since 320 is divisible by both 5 and 8, it is divisible by 40. </p>
8 <p><strong>Step 3:</strong>Since 320 is divisible by both 5 and 8, it is divisible by 40. </p>
