Greatest Common Factor
We found the factors 684,112,918 . The biggest common factor number is the GCF number.
So the greatest common factor 684,112,918 is 2.
Lets's calculate LCM of 17,54,245
Given numbers has no common factors except 1. So, there LCM is their product i.e 224910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/224910
Therefore, the GCF of Fractions 684/17,112/54,918/245 is 2/224910
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 17,54,245 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,54,245) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,54,245) x common factors =1 x 1 = 1
LCM(17,54,245) = ( 17 × 54 × 245 ) / 1
LCM(17,54,245) = 224910 / 1
LCM(17,54,245) = 224910
