Lets's calculate LCM of 392,381
Given numbers has no common factors except 1. So, there LCM is their product i.e 149352
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/149352
Therefore, the GCF of Fractions 543/392,2646/381 is 3/149352
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 392,381 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(392,381) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(392,381) x common factors =1 x 1 = 1
LCM(392,381) = ( 392 × 381 ) / 1
LCM(392,381) = 149352 / 1
LCM(392,381) = 149352
