Divisibility of a number by 4 Example: 85736 = 21434. (End two digit divisible by 4).So the number is divisible by 4. Example: 58648 / 4 = 14662. (End two digit divisible by 4).So the number is divisible by 4. Example: 85728 / 4 = 21432. (End two digit divisible by 4).So the number is divisible by 4. Example: 3571916 / 4 = 892979. (End two digit divisible by 4).So the number is divisible by 4. Example: 4781204 / 4 = 119530. (End two digit divisible by 4).So the number is divisible by 4. Note: The number is divisible by 4 if the end of two digit from right end is Zero. Example: 98300 = 24575 (End of both digit is Zero).So the number is divisible by 4. Example: 8573600 = 2143400.(End of both digit is Zero).So the number is divisible by 4. Example: 5864800 / 4 = 1466200.(End of both digit is Zero).So the number is divisible by 4. Example: 8572800 / 4 = 2143200.(End of both digit is Zero).So the number is divisible by 4. Example: 357191600 / 4 = 89297900.(End of both digit is Zero).So the number is divisible by 4. Example: 478120400 / 4 = 119530100.(End of both digit is Zero).So the number is divisible by 4. Note: So Before going to divisible by 4 any number, first check the end of two digit is from right end is divisible by 4 or end of two digit is Zero.Than all numbers is divisible by 4.
