Greatest Common Factor
We found the factors 34,638,980 . The biggest common factor number is the GCF number.
So the greatest common factor 34,638,980 is 2.
Lets's calculate LCM of 839,563,820
Given numbers has no common factors except 1. So, there LCM is their product i.e 387332740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/387332740
Therefore, the GCF of Fractions 34/839,638/563,980/820 is 2/387332740
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 839,563,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(839,563,820) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(839,563,820) x common factors =1 x 1 = 1
LCM(839,563,820) = ( 839 × 563 × 820 ) / 1
LCM(839,563,820) = 387332740 / 1
LCM(839,563,820) = 387332740
