2)
Thus 462 is divisible by 3 since 4 + 6 + 2 = 12 is divisible by 3.
461 is not divisible by 3 since 4+6+1 -11 is not divisible by 3.
2. A number is divisible by 3 if the sum of its digits is divisible by 3,
3. A number is divisible by 4 if the number formed by the tens and ones de
is divisible by 4.
3652 is divisible by 4 since 52 is divisible by 4.
3654 is not divisible by 4 since 54 is not divisible by 4.
4. A number is divisible by 5 if it has 0 or 5 in its ones place,
2340.4845 are divisible by 5. 2342, 4846 are not divisible by 5.
5. A number is divisible by 10 if it has 0 in its ones place.
3840, 485030 are divisible by 10. 3845, 485032 are not divisible by 10.
6. A number is divisible by 9 if the sum of its digits is divisible by 9.
Thus 3843 is divisible by 9 since 3 +8+4+3 = 18 is divisible by 9.
3849 is not divisible by 9 since 3 +8+4 + 9 = 24 is not divisible by 9.
7. A number is divisible by 15 if it is divisible by both 3 and 5.
14265 is divisible by both 3 and 5. Therefore it is divisible by 15.
Notice that 3 and 5 are factors of 15 and they are coprime.
