Greatest Common Factor
We found the factors 351,390 . The biggest common factor number is the GCF number.
So the greatest common factor 351,390 is 39.
Lets's calculate LCM of 55,4144
Given numbers has no common factors except 1. So, there LCM is their product i.e 227920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 39/227920
Therefore, the GCF of Fractions 351/55,390/4144 is 39/227920
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 55,4144 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,4144) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(55,4144) x common factors =1 x 1 = 1
LCM(55,4144) = ( 55 × 4144 ) / 1
LCM(55,4144) = 227920 / 1
LCM(55,4144) = 227920
