Number of factors
 

Is there a way to ow howman priimes factor MAXIMUM can have a value


For exemple ea value with 20 digits can hava how many primes facctor

The diggits number, the root....
Thanks

[TEX][\log_2(n)][/TEX] if your number is n, i.e. for a 20 decimal digit number [TEX][\log_2(10^{20}-1)] = 66[/TEX]. If you want different prime factors, search the largest product of the first primes that is <= n and count the factors:

10^20-2*3*5*7*11*13*17*19*23*29*31*37*41*43*47*53 > 0
10^20-2*3*5*7*11*13*17*19*23*29*31*37*41*43*47*53*59 < 0

Therefore you can have a maximum of 16 different prime factors.

It was just to set the size of and array...
