:1,3,7,21,41,123,287,861
Greatest Common Factor
We found the factors 617,861 . The biggest common factor number is the GCF number.
So the greatest common factor 617,861 is 1.
Lets's calculate LCM of 988,669
Given numbers has no common factors except 1. So, there LCM is their product i.e 660972
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/660972
Therefore, the GCF of Fractions 617/988,861/669 is 1/660972
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 988,669 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(988,669) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(988,669) x common factors =1 x 1 = 1
LCM(988,669) = ( 988 × 669 ) / 1
LCM(988,669) = 660972 / 1
LCM(988,669) = 660972
