4. Now You Try:
Which number IS NOT
divisible by 2?
572
1464
249

5. WONDERFUL….!!!

6. Divisibility by 3
a number is divisible by 3 if
the sum of the digits is 3, 6
or 9
Example:123456
1+2+3+4+5+6=21
2+1=3[which is divisible by
3]

7. Now You Try:
Which number IS NOT
divisible by 3?
572
1464

by 5]

10. Now You Try:
Which number IS NOT
divisible by 5?
9820
779

11. Good..!!

12. Divisibility by 9
A number is divisible by 9
if
the sum of all the digits will
add to 9
Example:50832=5+0+8+3+
2=18
1+8=9[which is divisible by
9]

13. NowYouTry:
Find the number that
IS NOT divisible
by 9.
