How to compute LCM of fractional numbers on paper?
 

Re: Lcm

Hi Faizan,
It should be LCM(numerators)/GCF(denominators)

Let me prove it for you.

Proof:
Let the fractions be a/b and c/d.
Now LCM(a,c) is divisible by a & c.
Now GCF(b,d) divides both b & d.

Hence the fraction LCM(a,c)/GCF(b,d) when divided by both a/b and c/d will
yeild a Natural number.

Where
LCM stands for Least Common Multiple.
GCF stands for Greatest Common Factor repectively.
