Greatest Common Factor
We found the factors 96,78,38,85 . The biggest common factor number is the GCF number.
So the greatest common factor 96,78,38,85 is 1.
Lets's calculate LCM of 76,47,85,81
Given numbers has no common factors except 1. So, there LCM is their product i.e 24593220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/24593220
Therefore, the GCF of Fractions 96/76,78/47,38/85,85/81 is 1/24593220
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 76,47,85,81 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,47,85,81) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(76,47,85,81) x common factors =1 x 1 = 1
LCM(76,47,85,81) = ( 76 × 47 × 85 × 81 ) / 1
LCM(76,47,85,81) = 24593220 / 1
LCM(76,47,85,81) = 24593220
Here are some samples of GCF of Fractions calculations.
