I suggest you to read through my thread " An algorithm to generate primes " .
You will find our similarity and difference .
Wants some suggestion on
If mod(Prime B ,Pn*)>1 then result will be Small Prime A in proper Range.
where Pn* is multiplication of all prime number less the nth prime number Ex 6,30,210,2310,30030,510510,9699690,….Pn*. Prime B>Pn*
Range of Prime B
3*=6 gives prime 3>=p<9
5*=30 gives prime 5>=p<=25
7*=210 gives prime 7>=p<=49
11*=2310 gives prime 11>=p<=121
.
.
.
.
Pn*=...gives prime Pn*>=p<=(Pn)^2
Ex
6 gives prime 3>=p<9
Mod (23,6)= 5 ; Mod (29,6)= 5 ;
30 gives prime 5>=p<=25
Mod(157,30)=7: Mod(163,30)=13: Mod(167,30)=17; Mod(173,30)=23
210 gives prime 7>=p<=49
Mod(223,210)=13; Mod(227,210)=17; Mod(229,210)=19; Mod(233,210)=23; Mod(239,210)=29;Mod(241,210)=31; Mod(251,210)=41

I suppose 49 is prime too, by the same logic?
No dear How you have calcluted can u explain...you have made mistake.:cool
take example of consecutive prime there mod with 30,210,2310 will give prime in range .Range is given in table.
consecutive prime MOD 30 (5 < prime< 25 ) MOD 210 ( 7 < prime < 49 ) Mod 2310 (11< pprime < 121 )

now ok, if we have big prime we can find out smaller one.
in general big primes yeilds smaller one........:d
Very good.

Is 9831655609 prime?
9831655609 ( MOD 30)=19 PRIME

Not true. I have some carrots.

This directly Means if you have big prime number with help of mod smaller can be find out.
]]>Hi;
Let me see it when you have it.
i will have to check 15 digits number (7777) times to get result.
