35/6 , remainder 5 but this is not prime number, be clear.

[amitgangurde]

Sir and for what we are adding 2 numbers on 189 .If we divided 189 ÷ 6 the answer is 3 so it is not a prime number you said that check the reminder if reminder is 1, 5 then it is prime number naa then if the reminder is 3 so the number 189 is not prime number only na

[hammadshut]

⚠⚠❌❌ Stop Spreading wrong information, this video is misleading and that is not a "trick" at all, when you divide 1001 by 6, the remainder is 5, but still 1001 is not a prime number (1001 is divisible by 7), STOP MAKING THESE KIND OF NONSENSE ''TRICK'' VIDEOS PLEASE.
Or even if you are showing "maths tricks" lay down the full conditions in which it can be

[yyyftyfyhffm]

sir agar 91 ko 6 sa divide krya ga toh remainder 1 aata ha but 91 is divisible by 13

[ishanushka]

But by dividing 24432443 by 6 the remainder is 5 so it should be a prime no 24432443 is not a prime no

[HarshTak-jo]

The exact trick is this that if we get remainder 1 or 5 after dividing a number by 6 then the number may or may not be a prime number, but if we get some other remainder like 2, 3, 4 then the number is definitely not a prime number.

[motaharhossain]

77/6 remainder 5.according to your rules 77should be prime number.bt we know 77is not prime number

[Mairrre-yc]

You said that when a number is divided ➗️ by 6 and the remainder is 1 or 5, it's prime, but that's wrong.
Here's a whole list of numbers that proves you wrong liar !!


_Remainder 1 when divided by 6:_

- 61 (prime)
- 67 (prime)
- 73 (prime)
- 79 (prime)
- 91 (not prime: 7 × 13)
- 97 (prime)
- 103 (prime)
- 109 (prime)
- 121 (not prime: 11 × 11)

_Remainder 5 when divided by 6:_

- 71 (prime)
- 83 (prime)
- 89 (prime)
- 101 (prime)
- 107 (prime)
- 113 (prime)
- 119 (not prime: 7 × 17)
- 131 (prime)

[amitgangurde]

But sir why we are adding that 2 numbers in 189

[Jandullah-]

Wrong! 841 divided by 6 give remainder 1 but isn't prime and is a perfect square of 29

[dronamrajuchanda]

wrong concept . Every prime number can be witten in the form of 6n+1 or 6n-1 (which gives remainder 1 or 5) but converse need not be true. Mr Anand you are using converse.

[kalpanasoni]

This is not working.... Bcoz if we take the number 527 and deviding it by 6, the remainder comes 5...so it should be a prime number but 527 is not a prime number

[kaneezfatima]

if we divide 143 by 6 we get 5 as per you itz a prime number sir, but actually 143 is not a prime number

[gauravsharma]

Wrong. Think twice before teaching such wrong tricks. As per your concept 35 should be prime, 65 should be prime but they are not. 35 and 65 when divided by 6 leaves remainder of 5 but they are not prime numbers. There are many more examples.

[latamendhe]

Yes 193 is a prime number as the remainder is 1

[zuberm]

65 is not a prime number but its remainder is 5. How it is ?

[nirupamaraghothaman]

If we divide 98765 by 6 we will get remainder 5 but still it is not a prime no

[adarshshrivastav]

extremely wrong trick spreading wrong information by teachers is not appreciable.. take 77 and divide it by 6 we get remainder 5 so acc. to ur trick 77 should be prime no. but its not prime no.

[SunandoDas-kr]

Please try 119 by your rule. All the time your rule will not work.

[aithanavenirajkumar]

91 is not prime number but its remainder is 1.Wrong trick
