___________
Let's explore more ::-
• Divisibility of 2 ::- The numbers which are even are divisible by 2. e.g- 2,4,6......etc.
•Divisibility of 3 ::- If the sum of all the digits are divisible by 3 , the whole number is divisible by 3.
e.g- 348 = 3 + 4 + 8 = 15 , sum is divisible by 3 so , number is also divisible by 3.
•Divisibility by 4 ::- If the last two digits of a number is divisible by 4 , the number will be divisible by 4. e.g- 124316 last two digits are 1 and 6 and hence b, it is divisible by 4.
• Divisibility of 5 ::- If the last digit of a number is 0 or 5 the number is divisible by 5. e.g- 10 , 15...etc.
• Divisibility of 6. ::- If the number is divisible by 2 and 3 it will be divisible by 6. e.g - 18, 24...etc.
• Divisibility of 7 ::- To check if a number is divisible by 7 take the last digit of number and double it and subtract it from the rest of the number. If the result after subtraction is divisible by 7 so the given number will be divisible by 7.
e.g.- 35 , 42 ...etc.
• Divisibility by 8 ::- If the last three digits of a number is divisible by 8 so the given number will be divisible by 8. e.g - 64, 16..etc.
• Divisibility of 9 ::- If the sum of the given number will be divisible by 9 the whole number will be divisible 9. e.g- 91 , 27 .. etc.
• Divisibility of 10 ::- if the last digit of a number will ends with zero it is divisible by 10. e.g- 10 , 20..etc
Answer:
Hey Mate!!
Here is you answer.
Step-by-step explanation:
(i) Divisibility test of 3 = Sum of No. should equal to multiple of of 3
so, for 709
7+0+9 = 16
16 is not a multiple of 3.
Thus, it is not divisible by 3.
(ii) Divisibility test of 4 = The last 2 digit of the No. should be multiple of 4
so, for 709
Last 2 digits = 09
09 is not a multiple of 4.
Thus, it is not divisible by 4.
