Lets's calculate LCM of 835,978
Given numbers has no common factors except 1. So, there LCM is their product i.e 816630
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/816630
Therefore, the GCF of Fractions 427/835,4780/978 is 1/816630
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 835,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(835,978) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(835,978) x common factors =1 x 1 = 1
LCM(835,978) = ( 835 × 978 ) / 1
LCM(835,978) = 816630 / 1
LCM(835,978) = 816630
