command #1: divisibility by 2 A amount is dissociative by 2 if its uttermost digit is 0,2,4,6,or 8. For instance, 8596742 is severable by 2 because the las t digit is 2. find oneself # 2: divisibility by 3: A physique is cleavable by 3 if the sum of its digits is severable by 3 For instance, 3141 is cleavable by 3 because 3+1+4+1 = 9 and 9 is divisible by 3. practice # 3: divisibility by 4 A number is divisible by 4 if the number delineated by its cash in ones chips dickens digits is divisible by 4. For instance, 8920 is divisible by 4 because 20 is divisible by 4. Rule #4: divisibility by 5 A number is divisible by 5 if its farthermost digit is 0 ot 5. For instance, 9564655 is divisible by 5 because the survively digit is 5. Rule # 5: divisibility by 6 A number is divisible by 6 if it is divisible by 2 and 3. Be careful! it is not one(a) or the other. The number must be divisible by both 2 and 3 before you can bring to an e nd that it is divisible by 6. Rule # 6: divisibility by 7 To ckeck divisibility rules for 7, exact care in fully the following two examples: Is 348 divisible by 7? Remove the last digit, which is 8. The number becomes 34. Then, doubled 8 to clear 16 and take up out the ground 16 from 34. 34 ? 16 = 18 and 18 is not divisible by 7. Therefore, 348 is not divisible by 7 Is 37961 divisible by 7?

Remove the last digit, which is 1. The number becomes 3796. Then, copy 1 to concentrate 2 and figure 2 from 3796. 3796 ? 2 = 3794, so still too mountainous? Thus replicate the process. Remove the las t digit, which is 4. The number becomes 379.! Then, Double 4 to get 8 and subtract 8 from 379. 379 ? 8 = 371, so still too big? Thus repeating the process. Remove the last digit, which is 1. The number becomes 37. Then, Double 1 to get 2 and subtract 2 from 37. 37 ? 2 = 35 and 35 is divisible by 7. Therefore, 37961 is divisible by 7. Rule #7:divisibility by 8 A number is divisible by 8 if the number represented by its last trio digits is divisible by 8. For instance, 587320 is...If you want to get a full essay, order it on our website: OrderCustomPaper.com
