Lets's calculate LCM of 135,977
Given numbers has no common factors except 1. So, there LCM is their product i.e 131895
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/131895
Therefore, the GCF of Fractions 690/135,4360/977 is 10/131895
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 135,977 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(135,977) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(135,977) x common factors =1 x 1 = 1
LCM(135,977) = ( 135 × 977 ) / 1
LCM(135,977) = 131895 / 1
LCM(135,977) = 131895
