Knowing the divisibility rules also makes it easier to know if a there will be a remainder. Divisibility Rule of 2 Any number ending in 0,2,4,6, or 8 is divisible by 2. Example: 468 divided by 2= 234 468 ends with 8 (an even number), then the entire number is divisible by 2. *also divisible by 3 and 9 Divisibility Rule of 3 Any number that gives a sum divisible by 3. Example: 690 divided by 3= 230 6+9+0=15 15 divided by 3= 5 so 690 is divided by 3. *also divisible by 2 and 5 Divisibility Rule for 5 Any number that ends with 0 or 5 is divisible by 5. Example: 5, 280 divided by 5=1,053 5,280 ends with 0, so the entire number (5,280) is divisible by 5. *also divisible by 2,3, and 5 Divisibility Rule of 6 If the number is divisible by 2 and 3, it is divisible by 6. Example 216 is an even number, so its divisible by 2 and it’s sum is 9, so it is divisible by 3. Divisibility Rule of 9 Any number that gives a sum divisible by 9. Example: 6,741 divided by 9=749 6+7+4+1=18 (18/2=9, therefore the entire number (6,741) is divisible by 9). *also divisible by 3 Divisibility Rule of 10 Any number that ends in 0 is divisible by 10. Example: 980 divided by 10= 98 980 ends with 0, so it is divisible by 10. *also divisible by 2 and 5 Try these… 1,458 682 945 2,700 681 Divisible by Divisible by 2 3 Divisible by Divisible by Divisible by Divisible by 5 6 9 10
