@ParthKohli any ideas?
Parth (parthkohli):
Diophantine equations.
Gotta hate them.
OpenStudy (anonymous):
I dont think the question is complete
Parth (parthkohli):
Well, do you need positive integer solutions?
OpenStudy (anonymous):
Yep. Smallest positive

Parth (parthkohli):
Oh yeah, how do you define smallest \(a,b,c\)?
OpenStudy (anonymous):
a b c are integers. no common factors
OpenStudy (anonymous):
did u mean a+b+c to be smallest
OpenStudy (anonymous):
that also works
Parth (parthkohli):
Oh, you need coprime a,b,c.

yep
OpenStudy (anonymous):
Can someone explain me what the real question is?
OpenStudy (anonymous):
what is the smallest amounts of 51 and 2 required to make a multiple of 84
Parth (parthkohli):
lol, I have \(a = b = c= 0\). ;-)
OpenStudy (anonymous):
perhaps I should have mentioned positive :D

51*2 + 2*33=84*2
OpenStudy (anonymous):
Oh wait...I did
Parth (parthkohli):
@sauravshakya Nailed it.
OpenStudy (anonymous):
Note: a must be even
OpenStudy (callisto):
smallest amount of 52 // smallest amount of 2 // small amount of 52 and 2?

Parth (parthkohli):
\[51a + 2b \equiv 0\pmod{84}\]So yup, \(a\) can't be odd.
OpenStudy (callisto):
That means smallest a / smallest b/ smallest c / smallest a+b ?
OpenStudy (anonymous):
8(51)+6(2) = 5(84)
OpenStudy (anonymous):
So u want to find minimum value of a+b+c???
OpenStudy (anonymous):
yes

But they aren't coprime. :-\
OpenStudy (anonymous):
Oh whoops, then I didn't mean coprime
As in like a,b,c don't have any common factors across the three of them
OpenStudy (anonymous):
It's all good then guys :D
