Greatest Common Factor
We found the factors 42,211,513 . The biggest common factor number is the GCF number.
So the greatest common factor 42,211,513 is 1.
Lets's calculate LCM of 38,79,677
Given numbers has no common factors except 1. So, there LCM is their product i.e 2032354
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2032354
Therefore, the GCF of Fractions 42/38,211/79,513/677 is 1/2032354
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 38,79,677 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,79,677) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(38,79,677) x common factors =1 x 1 = 1
LCM(38,79,677) = ( 38 × 79 × 677 ) / 1
LCM(38,79,677) = 2032354 / 1
LCM(38,79,677) = 2032354
