Q2 Using divisibility tests, determine which of the following numbers are divisible by 4; by 8: a b c d e f g h i j Answer: A number with 3 or more digits is divisible by 4 if the number formed by its last two digits is divisible by 4. A fishing tackle shops hull 10 with 3 or more digits is divisible by 8 if the number formed by its last three digits is divisible by 8.
The number is not divisible by 8. Hence, the number is divisible by 4 and 8. Hence, the number is not divisible by 4.
Hence the number is divisible by 4 and 8. The number is divisible by 4. Q3 Using divisibility tests, determine byjus class 6 maths chapter 3 mod of the following numbers are divisible by 6: a b c d e f g h i j Answer: a Since the last digit Of the byjus class 6 maths chapter 3 mod is 4, it is divisible by 2. On adding all the digits of the number, the sum obtained is Since 27 is divisible by 3, the given number is also divisible by 3.
As the number is divisible by both 2 and 3, it is divisible by 6. Since the last digit of the number is 8, it is divisible by 2. Since 16 is not divisible by 3, the given number is also not divisible by 3. As the number is not divisible by both 2 and 3, it is not divisible by 6. The last digit of the number is 5, which is not divisible by 2.
Therefore, the given number is also not divisible by 2. Since 15 is divisible by 3, the given number is also divisible by 3. The last digit of the number is 3, which is not divisible by 2. On adding all the digits Of the number, the sum obtained is Since the last digit of the number is 2, it is divisible by 2. Since 20 is not divisible by 3, the given number is also not divisible by 3.
Since the last digit of the number is O, it is divisible by 2. Since the last byjus class 6 maths chapter 3 mod of the number is 4, it is divisible by 2. Since 30 is divisible by 3, the given number is also divisible by 3. Since the last digit of the number is 3, it is not divisible by 2. Since 19 is not divisible by 3, the given number is also not divisible by 3. Since 21 is divisible by 3, the given number is also divisible by 3.
Since 23 is not divisible by 3, the given number is also not divisible by 3. Q4 Using divisibility tests, determine which of the following numbers are divisible by a b c d e f Therefore, is divisible by Therefore, is not divisible by To make the number divisible by 3, the sum of its digits should be divisible by 3. The smallest multiple of 3 which comes after 19 is As 24 is already divisible by 3, the smallest number that can be placed here is 0.
If we put 9, then the sum of the digits will be 33 and as 33 is divisible by fishing tackle shops hull 10, the number will also be divisible by 3. The number is divisible by 11 if the difference between the sum of the digits at odd places and the sum of the digits at even places is divisible by Q Find the common factors of: a 8, 20 b 9, Answer: The common factors of the following are: a 8, Hence, the common factors are.
