We found the factors 672,966 . The biggest common factor number is the GCF number.
So the greatest common factor 672,966 is 42.
Lets's calculate LCM of 158,915
Given numbers has no common factors except 1. So, there LCM is their product i.e 144570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 42/144570
Therefore, the GCF of Fractions 672/158,966/915 is 42/144570
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 158,915 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(158,915) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(158,915) x common factors =1 x 1 = 1
LCM(158,915) = ( 158 × 915 ) / 1
LCM(158,915) = 144570 / 1
LCM(158,915) = 144570
