Greatest Common Factor
We found the factors 56,205,597 . The biggest common factor number is the GCF number.
So the greatest common factor 56,205,597 is 1.
Lets's calculate LCM of 42,79,809
Given numbers has no common factors except 1. So, there LCM is their product i.e 2684262
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2684262
Therefore, the GCF of Fractions 56/42,205/79,597/809 is 1/2684262
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 42,79,809 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,79,809) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(42,79,809) x common factors =1 x 1 = 1
LCM(42,79,809) = ( 42 × 79 × 809 ) / 1
LCM(42,79,809) = 2684262 / 1
LCM(42,79,809) = 2684262
