Greatest Common Factor
We found the factors 74,34,56,64 . The biggest common factor number is the GCF number.
So the greatest common factor 74,34,56,64 is 2.
Lets's calculate LCM of 79,58,31,123
Given numbers has no common factors except 1. So, there LCM is their product i.e 17471166
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/17471166
Therefore, the GCF of Fractions 74/79,34/58,56/31,64/123 is 2/17471166
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 79,58,31,123 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,58,31,123) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,58,31,123) x common factors =1 x 1 = 1
LCM(79,58,31,123) = ( 79 × 58 × 31 × 123 ) / 1
LCM(79,58,31,123) = 17471166 / 1
LCM(79,58,31,123) = 17471166
Here are some samples of GCF of Fractions calculations.
