Lets's calculate LCM of 122,687
Given numbers has no common factors except 1. So, there LCM is their product i.e 83814
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/83814
Therefore, the GCF of Fractions 372/122,428/687 is 4/83814
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 122,687 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(122,687) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(122,687) x common factors =1 x 1 = 1
LCM(122,687) = ( 122 × 687 ) / 1
LCM(122,687) = 83814 / 1
LCM(122,687) = 83814
