We have: \(a=GCF\left(72,48\right)=24=2^3\cdot3\)

We have: \(b=GCF\left(108,144\right)=36=2^2\cdot3^2\)

So the least common multiple of a and b is: \(LCM\left(a,b\right)=LCM\left(24,36\right)=2^3\cdot3^2=8\cdot9=72\)

ANSWER: 72

a=GCF(72;48)=24;b=GCF(108;144)=36a=GCF(72;48)=24;b=GCF(108;144)=36

LCM(a;b)=72

\(a=GCF\left(72;48\right)=24;b=GCF\left(108;144\right)=36\)

\(LCM\left(a;b\right)=72\)
