Lets's calculate LCM of 19,31,977,519
Given numbers has no common factors except 1. So, there LCM is their product i.e 298660107
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/298660107
Therefore, the GCF of Fractions 2/19,42/31,20/977,468/519 is 2/298660107
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 19,31,977,519 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,31,977,519) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,31,977,519) x common factors =1 x 1 = 1
LCM(19,31,977,519) = ( 19 × 31 × 977 × 519 ) / 1
LCM(19,31,977,519) = 298660107 / 1
LCM(19,31,977,519) = 298660107
