→ Divisibility of 6 => A number is divisible by 6 if it is divisible by 2 and 3 both.
→ Divisibility of 2 => The divisibility rule for two states that any number with the last digit of 0, 2, 4, 6, or 8 will be divisible by 2.
→ Divisibility of 3 => If the sum of the digits of a number is divisible by 3, then the number is divisible by 3. Some examples of numbers divisible by 3 are as follows. The number 85203 is divisible by 3 because the sum of its digits 8+5+2+0+3=18 is divisible by 3.
(a) 34920 →
- 34920,0 is divisible by 2.
- 3+4+9+2+0 = 20 is not divisible by 3.
- This is not divisibility by 6 because this is not divisible by 3.
(b) 541212 →
- 541212, 2 is divisible by 2.
- 5+4+1+2+1+2 = 15 is divisible by 3.
- This is divisibility by 6.
(c) 360123 →
- 360123, 3 is not divisible by 2
- 3+6+0+1+2+3 = 15 is divisible by 3
- This is not divisibility by 6 because this is not divisible by 2
(d) 54903 →
- 54903, 3 is not divisible by 2
- 5+4+9+0+3 = 21 is divisible by 3
- This is not divisibility by 6 because this is not divisible by 2
