Greatest Common Factor
We found the factors 420,989 . The biggest common factor number is the GCF number.
So the greatest common factor 420,989 is 1.
Lets's calculate LCM of 241,375
Given numbers has no common factors except 1. So, there LCM is their product i.e 90375
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/90375
Therefore, the GCF of Fractions 420/241,989/375 is 1/90375
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 241,375 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(241,375) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(241,375) x common factors =1 x 1 = 1
LCM(241,375) = ( 241 × 375 ) / 1
LCM(241,375) = 90375 / 1
LCM(241,375) = 90375
