Greatest Common Factor
We found the factors 781,139,621 . The biggest common factor number is the GCF number.
So the greatest common factor 781,139,621 is 1.
Lets's calculate LCM of 497,237,211
Given numbers has no common factors except 1. So, there LCM is their product i.e 24853479
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/24853479
Therefore, the GCF of Fractions 781/497,139/237,621/211 is 1/24853479
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 497,237,211 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(497,237,211) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(497,237,211) x common factors =1 x 1 = 1
LCM(497,237,211) = ( 497 × 237 × 211 ) / 1
LCM(497,237,211) = 24853479 / 1
LCM(497,237,211) = 24853479
