:1,421
Greatest Common Factor
We found the factors 208,421 . The biggest common factor number is the GCF number.
So the greatest common factor 208,421 is 1.
Lets's calculate LCM of 616,533
Given numbers has no common factors except 1. So, there LCM is their product i.e 328328
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/328328
Therefore, the GCF of Fractions 208/616,421/533 is 1/328328
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 616,533 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(616,533) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(616,533) x common factors =1 x 1 = 1
LCM(616,533) = ( 616 × 533 ) / 1
LCM(616,533) = 328328 / 1
LCM(616,533) = 328328
