So the greatest common factor 215,320 is 5.
Lets's calculate LCM of 420,671
Given numbers has no common factors except 1. So, there LCM is their product i.e 281820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/281820
Therefore, the GCF of Fractions 215/420,320/671 is 5/281820
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 420,671 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,671) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(420,671) x common factors =1 x 1 = 1
LCM(420,671) = ( 420 × 671 ) / 1
LCM(420,671) = 281820 / 1
LCM(420,671) = 281820
