Divisibility Rules for 6

The video tutorial explains how to determine if a whole number is divisible by 6. It begins by reviewing the rules for divisibility by 2 and 3, stating that a number is divisible by 2 if its last digit is even, and by 3 if the sum of its digits is divisible by 3. To check for divisibility by 6, a number must meet both criteria. The tutorial provides examples with numbers 72 and 314 to illustrate these concepts, showing that 72 is divisible by 6 while 314 is not. The lesson concludes with a summary of these rules.

Explain why the number 72 is divisible by 6.

Why is the number 314 not divisible by six?
