In this guide, we&#8217;ll walk through the divisibility rules for numbers 1 to 10, and we&#8217;ll provide clear examples for each rule.<\/p>\n\n\n\n<p><strong>1. Divisibility by 1: The Universal Divisor<\/strong> Any integer is divisible by 1, regardless of its value.<\/p>\n\n\n\n<p><strong>2. Divisibility by 2: The Even-Odd Test<\/strong> If the last digit of a number is even (0, 2, 4, 6, or 8), the number is divisible by 2.<\/p>\n\n\n\n<p>Examples:<\/p>\n\n\n\n<ul>\n<li><strong>146:<\/strong> The last digit is 6 (even), so 146 is divisible by 2.<\/li>\n\n\n\n<li><strong>231:<\/strong> The last digit is 1 (odd), so 231 is not divisible by 2.<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Divisibility by 3: The Digit Sum Criterion<\/strong> If the sum of the digits of a number is divisible by 3, the number itself is divisible by 3.<\/p>\n\n\n\n<p>Examples:<\/p>\n\n\n\n<ul>\n<li><strong>183:<\/strong> Digit sum = 1 + 8 + 3 = 12 (divisible by 3), so 183 is divisible by 3.<\/li>\n\n\n\n<li><strong>427:<\/strong> Digit sum = 4 + 2 + 7 = 13 (not divisible by 3), so 427 is not divisible by 3.<\/li>\n<\/ul>\n\n\n\n<p><strong>4. Divisibility by 4: The Last Two Digits Rule<\/strong> If the two-digit number formed by the last two digits of a number is divisible by 4, the whole number is divisible by 4.<\/p>\n\n\n\n<p>Examples:<\/p>\n\n\n\n<ul>\n<li><strong>932:<\/strong> The last two digits, 32, are divisible by 4, so 932 is divisible by 4.<\/li>\n\n\n\n<li><strong>675:<\/strong> The last two digits, 75, are not divisible by 4, so 675 is not divisible by 4.<\/li>\n<\/ul>\n\n\n\n<p><strong>5. Divisibility by 5: The Zero or Five Check<\/strong> If the last digit of a number is 0 or 5, the number is divisible by 5.<\/p>\n\n\n\n<p>Examples:<\/p>\n\n\n\n<ul>\n<li><strong>540:<\/strong> The last digit is 0, so 540 is divisible by 5.<\/li>\n\n\n\n<li><strong>763:<\/strong> The last digit is 3, so 763 is not divisible by 5.<\/li>\n<\/ul>\n\n\n\n<p><strong>6. Divisibility by 6: The Combo Rule<\/strong> A number is divisible by 6 if it is divisible by both 2 and 3.<\/p>\n\n\n\n<p>Examples:<\/p>\n\n\n\n<ul>\n<li><strong>342:<\/strong> Divisible by 2 (last digit is even) and by 3 (digit sum = 3 + 4 + 2 = 9), so 342 is divisible by 6.<\/li>\n\n\n\n<li><strong>516:<\/strong> Divisible by 2 (last digit is even) but not by 3 (digit sum = 5 + 1 + 6 = 12), so 516 is not divisible by 6.<\/li>\n<\/ul>\n\n\n\n<p><strong>7. Divisibility by 7: The Division Dilemma<\/strong> Divisibility by 7 is trickier and often requires direct division or more advanced methods.<\/p>\n\n\n\n<p><strong>8. Divisibility by 8: The Last Three Digits Criterion<\/strong> If the three-digit number formed by the last three digits of a number is divisible by 8, the whole number is divisible by 8.<\/p>\n\n\n\n<p>Examples:<\/p>\n\n\n\n<ul>\n<li><strong>2488:<\/strong> The last three digits, 488, are divisible by 8, so 2488 is divisible by 8.<\/li>\n\n\n\n<li><strong>7315:<\/strong> The last three digits, 315, are not divisible by 8, so 7315 is not divisible by 8.<\/li>\n<\/ul>\n\n\n\n<p><strong>9. Divisibility by 9: The Digit Sum Redux<\/strong> Similar to divisibility by 3, if the sum of the digits is divisible by 9, the number itself is divisible by 9.<\/p>\n\n\n\n<p>Examples:<\/p>\n\n\n\n<ul>\n<li><strong>621:<\/strong> Digit sum = 6 + 2 + 1 = 9 (divisible by 9), so 621 is divisible by 9.<\/li>\n\n\n\n<li><strong>478:<\/strong> Digit sum = 4 + 7 + 8 = 19 (not divisible by 9), so 478 is not divisible by 9.<\/li>\n<\/ul>\n\n\n\n<p><strong>10. Divisibility by 10: The Trailing Zero Principle<\/strong> Any number ending with 0 is divisible by 10.<\/p>\n\n\n\n<p>Examples:<\/p>\n\n\n\n<ul>\n<li><strong>930:<\/strong> Ends with 0, so 930 is divisible by 10.<\/li>\n\n\n\n<li><strong>742:<\/strong> Does not end with 0, so 742 is not divisible by 10.<\/li>\n<\/ul>\n\n\n\n<p>Mastering these divisibility rules can significantly simplify your math computations, whether you&#8217;re working with small or large numbers. By applying these rules and practicing with various examples, you&#8217;ll gain a valuable tool for your mathematical toolkit.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mastering Divisibility Rules: Simplifying Numbers 1 to 10 with Examples Understanding divisibility rules can demystify the world of numbers and make math much more manageable.
