Lets's calculate LCM of 29,83,679
Given numbers has no common factors except 1. So, there LCM is their product i.e 1634353
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1634353
Therefore, the GCF of Fractions 90/29,987/83,636/679 is 3/1634353
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 29,83,679 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(29,83,679) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(29,83,679) x common factors =1 x 1 = 1
LCM(29,83,679) = ( 29 × 83 × 679 ) / 1
LCM(29,83,679) = 1634353 / 1
LCM(29,83,679) = 1634353
