Greatest Common Factor
We found the factors 878,422 . The biggest common factor number is the GCF number.
So the greatest common factor 878,422 is 2.
Lets's calculate LCM of 320,671
Given numbers has no common factors except 1. So, there LCM is their product i.e 214720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/214720
Therefore, the GCF of Fractions 878/320,422/671 is 2/214720
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 320,671 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(320,671) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(320,671) x common factors =1 x 1 = 1
LCM(320,671) = ( 320 × 671 ) / 1
LCM(320,671) = 214720 / 1
LCM(320,671) = 214720
