Greatest Common Factor
We found the factors 76,711,445 . The biggest common factor number is the GCF number.
So the greatest common factor 76,711,445 is 1.
Lets's calculate LCM of 19,77,618
Given numbers has no common factors except 1. So, there LCM is their product i.e 904134
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/904134
Therefore, the GCF of Fractions 76/19,711/77,445/618 is 1/904134
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 19,77,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,77,618) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,77,618) x common factors =1 x 1 = 1
LCM(19,77,618) = ( 19 × 77 × 618 ) / 1
LCM(19,77,618) = 904134 / 1
LCM(19,77,618) = 904134
