So the greatest common factor 35,42,551 is 1.
Lets's calculate LCM of 821,778,615
Given numbers has no common factors except 1. So, there LCM is their product i.e 392823870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/392823870
Therefore, the GCF of Fractions 35/821,42/778,551/615 is 1/392823870
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 821,778,615 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(821,778,615) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(821,778,615) x common factors =1 x 1 = 1
LCM(821,778,615) = ( 821 × 778 × 615 ) / 1
LCM(821,778,615) = 392823870 / 1
LCM(821,778,615) = 392823870
