We found the factors 978,3453 . The biggest common factor number is the GCF number.
So the greatest common factor 978,3453 is 3.
Lets's calculate LCM of 867,7954
Given numbers has no common factors except 1. So, there LCM is their product i.e 6896118
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/6896118
Therefore, the GCF of Fractions 978/867,3453/7954 is 3/6896118
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 867,7954 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(867,7954) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(867,7954) x common factors =1 x 1 = 1
LCM(867,7954) = ( 867 × 7954 ) / 1
LCM(867,7954) = 6896118 / 1
LCM(867,7954) = 6896118
