<p><strong>Divisibility by 5:</strong>The unit’s place digit is 7. Therefore, 627 is not divisible by 5.</p>
36
<p><strong>Divisibility by 7:</strong>The last digit in 627 is 7. To check divisibility by 7, double the last digit (7 × 2 = 14). Then, subtract it from the rest of the number (62 - 14 = 48). Since 48 is not divisible by 7, 627 is also not divisible by 7.</p>

37
<p><strong>Divisibility by 11:</strong>In 627, the difference between the sum of the digits in odd positions (6 + 7 = 13) and the sum of the digits in even positions (2) is 11. This means that 627 is divisible by 11. Since 627 is divisible by 3 and 11, it has more than two factors.</p>
