Lets's calculate GCF of 211,305
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 211
:1,211
Now, list down the factors of 305
:1,5,61,305
Greatest Common Factor
We found the factors 211,305 . The biggest common factor number is the GCF number.
So the greatest common factor 211,305 is 1.
Lets's calculate LCM of 943,947
Given numbers has no common factors except 1. So, there LCM is their product i.e 893021
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/893021
Therefore, the GCF of Fractions 211/943,305/947 is 1/893021
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 943,947 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(943,947) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(943,947) x common factors =1 x 1 = 1
LCM(943,947) = ( 943 × 947 ) / 1
LCM(943,947) = 893021 / 1
LCM(943,947) = 893021
