Greatest Common Factor
We found the factors 54,12,856 . The biggest common factor number is the GCF number.
So the greatest common factor 54,12,856 is 2.
Lets's calculate LCM of 47,87,55
Given numbers has no common factors except 1. So, there LCM is their product i.e 224895
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/224895
Therefore, the GCF of Fractions 54/47,12/87,856/55 is 2/224895
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 47,87,55 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,87,55) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(47,87,55) x common factors =1 x 1 = 1
LCM(47,87,55) = ( 47 × 87 × 55 ) / 1
LCM(47,87,55) = 224895 / 1
LCM(47,87,55) = 224895
