Greatest Common Factor
We found the factors 478,158 . The biggest common factor number is the GCF number.
So the greatest common factor 478,158 is 2.
Lets's calculate LCM of 278,221
Given numbers has no common factors except 1. So, there LCM is their product i.e 61438
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/61438
Therefore, the GCF of Fractions 478/278,158/221 is 2/61438
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 278,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(278,221) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(278,221) x common factors =1 x 1 = 1
LCM(278,221) = ( 278 × 221 ) / 1
LCM(278,221) = 61438 / 1
LCM(278,221) = 61438
