Lets's calculate LCM of 543,892
Given numbers has no common factors except 1. So, there LCM is their product i.e 484356
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/484356
Therefore, the GCF of Fractions 779/543,420/892 is 1/484356
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 543,892 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(543,892) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(543,892) x common factors =1 x 1 = 1
LCM(543,892) = ( 543 × 892 ) / 1
LCM(543,892) = 484356 / 1
LCM(543,892) = 484356
