Answer 2

Answer:

The number is divisible by 2, 4, 5, 6 and not divisible by 3

Step-by-step explanation:

The number is 221840

Divisibility by 2

Since the last digit of the given number is '0', it is clearly divisible by 2

(The last digit should contain any of these digits for being divisible by 2; 0, 2, 4, 6, 8)

Divisibility by 3

The sum of the digits of the number is: 2+2+1+8+4+0 = 17. The no. 17 is not divisible by 3 and hence the given number is also not divisible by 3

(The sum of the digits of the number should be divisible by 3 for that number to divisible by 3)

Divisible by 4

The last two digits of the number (40) is divisible by 4 hence the given number is also divisible by 4

(The last two digits of the number should be divisible by 4 if the number is to be divided by 4)

Divisible by 5

The last digit of the number is '0' and hence this number is divisible by 5

(The last digit of the number should be 0 or 5 if the number is to be divisible by 5)

Divisible by 6

The number should be divisible by 2 and 3 if the number is to be divisible by 6. The number is not divisible by 3 and hence it is not divisible by 6

(The number should be divisible by 2 and 3 if the number is to be divisible by 6)
