11388 - GCD LCM

[arifcsecu]

Another One of the easiest problem like Hasmot the brave warrior:


we know that
a x b= gcd(a,b) x lcm(a,b)
or gcd(a,b) x lcm(a,b)= a x b ....................(1)

Input is :
gcd(a,b) and lcm(a,b)

output :
a=?
b=?
from equation (i)
there is symmetry

try:
from forward:
a=12
b=18

gcd(12,18)=6
lcm(12,18)=36

12 x 18 = 6 x 36

from reverse:
a=6
b=36
gcd(6,36)= 6
lcm(6,36)= 36

6 x 36 = 6 x 36
ha ha ha ............
just :
input = output if b is divisible by a
otherwise
print -1

Nice problem lol....sometimes simple problems require deep thinking

[raj]

Can anyone please explain me how can i know that a is minimized or not...

""output the pair for which a is minimized. In case there is no such pair, output -1.""

what does this sentence means??

if L%G!=0
print -1
else
print a=G and b=L
