\(y = 24z = 2^3*3*z\)
\(a = 10z = 2*5*z\)
\(LCM (y, a) = 2^3*3*5*z = 120z\)
Answer B
\(a = 10z = 2*5*z\)
\(LCM (y, a) = 2^3*3*5*z = 120z\)
Answer B

Hi,
y=24z may also imply that y is a three digit number with units place z...implying thereby
y= 242,243,245,247
why are we assuming that y=24z is 24*z....??
pl elaborate?
