Question

Check the divisibility of 1782 639210 61233 by 6​

Answer 1

Answer:

Fᴏʀ ᴄʜᴇᴄᴋɪɴɢ ᴛʜᴇ ᴅɪᴠɪsɪʙɪʟɪᴛʏ ʙʏ 6

We use

A number is divisible by 6,if it is divisible by 2 and 3

↗A number is divisible by 3 , if the sum of all digits is divisible by 3

↗A number is divisible by 2 , if the last digits are even.

So , if we want to check whether s number is divisible by 6 then that number must be divisible by 2 and 3 both , so it should fulfill the above property.

1) 1782 

Check whether 1782 is divisible by 2 or not

1782 = the last digit is even so it is divisible by 2.

Check whether it is divisible by 3

1+7+8+2 = 18

18 is divisible by 3. So 1782 is divisible by 3 also.

1782 is divisible by both 2 and 3

Sᴏ ɪᴛ ᴡɪʟʟ ᴀʙsᴏʟᴜᴛᴇʟʏ ᴅɪᴠɪsɪʙʟᴇ ʙʏ 6.

2) 639210

Check whether this number is divisible by 2

639210 = So it's last digit is even than it is divisible by 2.

Now check whether it is divisible by 3

6+3+9+2+1+0 = 21

21 is divisible by 3

Sᴏ 639210 ɪs ᴀʟsᴏ ᴅɪᴠɪsɪʙʟᴇ ʙʏ 6

3)61233

Check whether it is divisible by 2

61233 = last digit is not even so it is not divisible by 2

If a number is not divisible by either 2 or 3 then it will not divisible by 6

Sᴏ 61233 ɪs ɴᴏᴛ ᴅɪᴠɪsɪʙʟᴇ ʙʏ 6
